Merge, split, compress, sign and protect PDFs without handing a contract or a passport scan to someone else’s server. Every tool here runs in your own browser.
These tools cover the everyday PDF jobs: combine PDFs, pull out selected pages, make a PDF smaller, or add a signature. The work happens in your browser, so contracts, statements and scans stay on your device.
Combining a PDF and a photo explains the image-to-PDF step before merging. For only part of a file, the selected-page guide explains physical page numbering and ranges.
You can also protect a PDF with a password, remove the author and hidden details, add a watermark, number its pages, or save every page as an image. If you are unsure which route to take, the step-by-step guides start with the job rather than the tool name.
Strict PDF upload limits need a size check and a readability check: every compression preset makes page images and removes searchable text. A placed signature is a visible mark, not a verified certificate. Keep original documents and check the saved copy before sharing.
Most PDF jobs fall into three groups. To change what is in a document, use Merge to join files, Split to take pages out, Rotate & reorder to fix page order and direction, and Crop to trim margins. These copy the real pages, so text stays selectable and quality does not change.
To make a document smaller, Compress PDF redraws each page as a picture. That is very effective on scans and photographs, and it makes the text unselectable, so it is the wrong choice for a document you need to search. To get the words out, Extract text reads the text already in the PDF, and Image to text reads scans.
For sending, Protect PDF adds a password to open the file, Sign PDF places an image of your signature, and Remove PDF metadata clears the author and dates before you send it.
Merging, splitting, rotating, cropping, signing and adding page numbers keep the page content as it was. Converting a PDF to images, or compressing one, turns the page into a picture. Going from Word to PDF lays the document out again, so a check of the preview is worthwhile for complicated layouts.
None of the tools change your original. Each one gives you a new file, so you can try a setting, look at the result, and go back if it is not what you wanted.
The work happens in your browser, so the limit is your device’s memory rather than a rule on our side. A phone handles ordinary documents well, and a computer is better for long scanned PDFs. If a job fails, try fewer pages, or split the document first.
