Free Online PDF Tools
Merge, split, compress, and convert PDFs locally in your browser - free PDF tools with no uploads and no watermarks.
About PDF Tools
Combine files with Merge PDF, pull out pages with Split PDF, shrink a document with Compress PDF, or turn pages into pictures with PDF to Image.
Because everything runs on your device, confidential PDFs - contracts, statements, records - are never uploaded to an unknown server. There are no watermarks either.
Everything runs in your browser
This matters more for PDFs than for almost any other file type, because the documents people most often need to merge, split or compress are contracts, medical records, bank statements, identity documents and tax filings. Every PDF tool here processes files locally: nothing is uploaded to a server, nothing is stored, and nothing is retained after you close the page. It is worth checking this property of any online PDF tool before using it on confidential material, because many do upload.
Choosing the right operation
If a file is too large for an upload limit, try compressing before splitting — a 30 MB scan often reduces to under 6 MB by downsampling images, which serves the recipient far better than three files they must reassemble. If you need only part of a document, split or extract a page range. If you are assembling several documents for submission, merge and check the page order carefully: alphabetical file sorting puts ‘page10’ before ‘page2’, which is the most common error.
What to know before you start
- Digital signatures are invalidated by merging or splitting, because a signature attests to one exact document. This is the mechanism working correctly.
- Bookmarks and internal links frequently break, since they point at page numbers that have shifted.
- Removing a page does not always remove its content from the file's internal structure. For genuine redaction, use a dedicated redaction function and verify the output by searching it.
- Compression is not reversible. Keep the original and work on a copy.
Converting pages to images makes text unsearchable and unreadable by screen readers, which is a significant accessibility cost for a weak protection — OCR recovers the text readily.
Frequently Asked Questions
Are my PDF files uploaded to a server?
No. All PDF tools process your files in your browser, so your documents stay private on your device.
Do the tools add a watermark?
No. The output PDFs and images have no watermark.
Can I merge several PDFs into one?
Yes. The Merge PDF tool combines multiple files into a single document in the order you choose.
Are my PDFs uploaded to a server?
No. Every PDF tool here processes files entirely in your browser, so contracts, statements and identity documents never leave your device. This is worth verifying with any online PDF tool before using it.
Should I split or compress a file that is too large?
Compress first. A 30 MB scan often reduces to under 6 MB by downsampling images and converting to greyscale, which is far more useful to the recipient than several files they must reassemble.
Does deleting a page remove its content completely?
Not necessarily. Depending on the tool, content can persist in the file's internal structure. For confidential material, use a dedicated redaction function and verify by searching the output for text you expect to be gone.
