In-depth, expert guides on merging, compressing, converting, signing and securing PDF documents - all written for people who care about privacy and getting the details right.
Drop in two or more PDFs, put them in order, get one document - all in your browser’s memory. What the tool does, what it never does, and the details that matter for bookmarks and page sizes.
Type “1-3, 7, 12-14” and get exactly those pages as a new PDF. How range syntax works, what happens to the original, and why the file never leaves your machine.
Every page renders as a thumbnail; you drag them into the order you want and export. How the preview is generated locally and what it means for scanned documents.
Rotating in a viewer only changes how *you* see the file. This tool rewrites each page’s rotation entry so the fix travels with the document.
Save just the pages you need as a fresh PDF - the signature page of a contract, one chapter of a manual - with a page-range field and nothing else.
Strip blank scans, cover sheets, or pages that shouldn’t travel. The tool rebuilds the document without them - and because it runs locally, nobody else ever saw them.
Placeholder pages for double-sided printing, separator sheets for scanning batches, a canvas for annotation tools - generated in your browser at any page size.
N-up layout without a print driver: the tool draws several pages onto each new sheet, with sensible orientation. Great for handouts, terrible for 6pt footnotes - here’s the balance.
Mixed-size scans and US-Letter downloads that won’t print right on A4 - the tool rescales every page onto a uniform size, keeping proportions intact.
Scanned an open book and got two pages per image? This cuts every page down the middle and rebuilds the document in reading order.
Cut oversized margins, scanner borders, or punch-hole shadows off every page at once, with a live preview of the crop box before you commit.
A 200-page PDF without an outline is a scrolling exercise. Add titled bookmarks that jump to pages - the same sidebar outline readers expect from published documents.
Contract v3 vs v4: the tool renders both files and tints every changed region red, page by page, so nothing slips through - no uploads, no third party reading either version.
Draw one PDF on top of another - letterhead behind a letter, a DRAFT template over every page, typed answers over a scanned form.
Real PDF annotations - not text baked into the page - that show up in Acrobat, Preview and every serious reader, added entirely in your browser.
A PDF can tell the reader to open with the outline visible, fit the window, or hide the toolbar. Useful polish for documents you distribute.
Object streams, deduplication, and dead-weight removal - the honest mechanics of shrinking a PDF locally, and why results vary so much between files.
Flattening bakes every form field, annotation and layer into the page image itself - nothing left to edit, extract, or accidentally change. Here’s when you want that.
Truncated downloads and damaged cross-reference tables make readers give up on files that are mostly intact. The repair tool rebuilds the structure around the content it can recover.
Extracting paragraphs, headings and layout from a format that has none of those concepts - what the converter can reconstruct, where it guesses, and how to get the best .docx out.
The tool detects table geometry from text positions and rebuilds rows and columns as a real .xlsx. Works brilliantly on bank statements; here’s what trips it up.
Each page becomes a slide you can present or restyle. How the converter decides what’s a title, what’s body text, and what to render as an image.
Render every page at the DPI you choose - one image for a single page, a ZIP for many. The scale setting is the difference between crisp and blurry; here’s how to pick it.
Pull every word out of a PDF’s text layer into a clean .txt. Also the quickest way to discover whether your “document” is actually just a photograph.
Headings become #, lists become -, and the prose comes out ready for Obsidian, Notion or a RAG pipeline - converted entirely on your device.
One self-contained HTML file with the document’s structure preserved - readable on any device, indexable, and generated without a server.
PDFs fight small screens; EPUB reflows. How the converter extracts reading order and chapters so your Kobo or Kindle can typeset the text itself.
PDF/A is the ISO format archives and courts ask for - self-contained, no external dependencies. What the converter changes, and the honest trade-off it makes with fonts.
Print shops ask for CMYK with ink limits; toner budgets ask for grayscale. The tool converts colorspaces per-pixel using ICC profiles, right in the browser.
Your draft contracts and CVs shouldn’t tour a data center to become PDFs. How the local converter renders DOCX - and which Word features survive the trip.
Sheets sprawl; pages don’t. What the converter does with wide tables, multiple sheets, and formatting when turning .xlsx into a tidy PDF.
Feed it a saved .html file and get a paginated PDF - rendered by your own browser engine, which is exactly the engine HTML was made for.
READMEs, meeting notes and drafts written in Markdown become typeset PDFs with headings, lists and quotes intact - no LaTeX, no cloud.
Paste or type anything and get a clean, printable document with proper margins and page breaks. Simpler than a word processor, faster than a template.
Logos and diagrams exported as SVG render into PDF at high resolution - ready for print workflows that won’t accept an SVG file.
Receipts, whiteboard photos, ID scans - drop in any mix of images and get one ordered PDF, sized to the images themselves.
Photograph pages straight into a PDF from your phone or laptop camera. What makes a phone “scan” legible, and how the tool assembles the result locally.
Turn a saved HTML file into a pixel-perfect image - useful for email previews, documentation, and archiving how something looked.
A 15 MB neural network runs inside your tab, reads every page, and writes an invisible text layer under the scan. No uploads - the engine comes to the document.
The tool encrypts your document with AES-256 in the browser - the password never exists anywhere but your machine. Plus: what owner passwords and permissions actually enforce.
Typing the same password every time you open your own bank statement gets old. Decrypt once, locally, and save an unlocked copy - nothing is “cracked” and nothing is uploaded.
Text or image stamps, tiled or centered, at any opacity and angle. What a watermark protects against - and what it honestly doesn’t.
A black rectangle drawn over text is not redaction - the text is still there. This tool searches, removes, and rasterizes so the words are genuinely gone. Here’s the proof.
Author names, employer software versions, creation dates, sometimes full file paths - PDFs carry more than their pages. One pass removes it all, locally.
The difference between “Microsoft Word - final_v2_REAL.docx” and a real title in search results and reader tabs. Edit every metadata field in place.
Draw your signature, place it on the page, export. Where a drawn signature is legally fine, where it isn’t, and why doing it locally matters for documents worth signing.
The tool reads the form fields embedded in the PDF and gives you real inputs to type into. Flatten when you’re done so answers can’t be edited downstream.
Built to pair with PDF encryption: cryptographically random passwords generated on-device, with the entropy shown in bits - and an explanation of what that number means.
Add text boxes, images, highlights and shapes onto any page with a full canvas editor - the kind of quick edit that never justified an Acrobat license.
Quality sliders, format choices, and the perceptual sweet spot around 75-85% - how the browser shrinks a photo by 80% without visible damage.
Pixel-exact resizing with aspect ratio locked or free - for upload limits, thumbnails, and print sizes, computed entirely on your device.
Drag a crop box, or type exact coordinates when precision matters. Nothing but the pixels you keep ends up in the output file.
Fix sideways phone photos in one tap - 90°, 180°, 270°, or mirrored. The tool re-encodes once, at full quality.
iPhone HEIC files that websites reject, PNGs ten times larger than they need to be - one conversion makes them open everywhere.
PNG won’t recover detail JPG already discarded - but for editing, transparency work, and stopping generational quality loss, converting up is the right move.
Double or quadruple an image’s resolution with smooth interpolation - for old photos, small logos, and print jobs that need more pixels than you have.
Background removal that runs on your device - how the tool separates subject from backdrop and hands you a transparent PNG.
A face-detection model runs in your browser, finds every face, and blurs them beyond recovery - the one anonymization workflow where uploading would defeat the purpose.
Stamp your name or logo across images at any opacity - tiled or placed - so screenshots and reposts carry your credit with them.
Brightness, contrast, saturation, filters, crop and rotate on a live canvas - a real editor for everyday fixes, running 100% in the browser.
Top text, bottom text, proper Impact-style stroke - and because it runs locally, your meme drafts stay between you and your conscience.
Photos, charts and logos live inside PDFs at their original resolution. Extract them all as files instead of taking blurry screenshots.
Most OCR failures are decided before the file ever reaches the software — at 150 DPI, in the lighting, and in the way the page was laid out. A practical guide to the settings that actually change the output, with a real example of text OCR gets wrong even on a clean scan.
Teams handling contracts, medical records and payroll keep arriving at the same conclusion: the safest document workflow is the one with no upload step. What that actually means in practice, where it genuinely does not work, and how to tell the two apart.
A comprehensive walkthrough covering everything from a simple two-file merge to assembling a 500-page legal exhibit binder, all without uploading a single byte to the cloud.
How table extraction actually works, why it sometimes fails, and a step-by-step process for converting bank statements, invoices, and audit reports to clean, formula-ready spreadsheets.
Three categories of e-signature, the legal frameworks behind them (ESIGN, eIDAS, UETA), when each one is actually appropriate, and a step-by-step signing workflow for everyday business documents.
A deep dive into how PDF files actually become huge, the four levers compression tools pull to shrink them, and how to choose the right preset for scans, contracts, and graphics-heavy reports.
Three split modes, four real workflows, and the redaction trap that catches most people. A complete guide to extracting exactly the pages you need.
Why our local engine is better at preserving your fonts and layout than standard cloud converters.
