About PDF & Document Tools
PDFs are the format documents end up in when they need to stop changing. That reliability is exactly what makes them frustrating to edit: the moment you need to combine two files, drop a page, or shrink one down to fit an upload limit, you are usually reaching for software you do not have.
These tools do the common PDF jobs directly in your browser. Merging, splitting, rotating, reordering, compressing, converting to and from images, adding page numbers or watermarks, and locking files with a password. No account, no watermark stamped on your output, no queue.
The privacy difference is the reason this category exists. Most free PDF sites upload your document to their servers, process it there, and give you a download link — which means your file sat on infrastructure you do not control, sometimes for hours. For a holiday photo album that may not matter. For a signed contract, a medical record, a passport scan, or a bank statement, it very much does. Every tool here reads your file into browser memory, does the work locally, and hands the result straight back.
The practical consequence is that nothing is ever transmitted, so there is no upload wait and no file-size ceiling imposed by someone else's bandwidth bill. The only real limit is your own device's memory, which on a modern phone or laptop comfortably handles documents far larger than most upload-based services will accept.
Why PDFs resist editing
A PDF is not a document in the way a Word file is. It is closer to a set of printing instructions: place this glyph at these coordinates, draw this line here, using this embedded font. There is often no stored notion of a paragraph, a heading, or even a word — just positioned marks that happen to look like text when rendered.
This is why editing a sentence in the middle of a PDF is genuinely hard while reordering whole pages is easy, and why extracted text sometimes arrives with words run together or in the wrong reading order. Operations that work on whole pages — merge, split, rotate, delete, watermark — are reliable precisely because they leave each page's internal instructions untouched.
What compression actually does
Most of the size in a large PDF is images, not text. Compression works primarily by re-encoding those images at a lower quality or resolution, which is why a scanned document can often be shrunk by ninety percent while a text-only report barely moves — there was nothing large to compress in the first place.
This makes compression lossy and irreversible. Once image data is discarded it cannot be recovered by decompressing, so keep the original if the document has any archival value. If a scan needs to stay legible for small print or a signature, compress conservatively and check the result at full zoom before sending it on.
Frequently asked questions
Are my PDFs uploaded to your servers?
No. Every PDF tool here runs entirely in your browser. Your file is read into memory on your own device, processed locally, and the result is handed straight back. Nothing is transmitted, stored, or retained. This is the main difference between these tools and most free PDF sites, which upload your document and process it server-side.
Is there a file size limit?
None imposed by us. Because your file never travels anywhere, there is no bandwidth cost to cap. The practical limit is your device's available memory — a modern laptop or phone handles documents well beyond what most upload-based services accept. Very large files simply take a little longer to process.
Will merging or splitting reduce quality?
No. Merging, splitting, rotating, reordering, extracting and deleting pages are all lossless — the page content is copied across unchanged. Only compression and conversion to images are lossy, and both are clearly marked as such on their own pages.
Can I remove a password I have forgotten?
No. The unlock tool removes password protection from a document you can already open, which is useful when you need to send a file onward without the recipient needing the password. It cannot break encryption or recover a password you do not know, and it should only be used on documents you are authorised to access.
