Which tools change your file, and which do not
Worth knowing before you pick one, because it is the difference between a reversible edit and a permanent one.
| Tool | Lossless? | What happens |
|---|---|---|
| Merge | Yes | Page objects are copied between documents |
| Split | Yes | Page objects are copied into a new document |
| Rotate | Yes | A number in the page metadata changes |
| Compress — Lossless mode | Yes | Metadata stripped, file structure repacked |
| Delete pages | Yes | Remaining page objects are copied unchanged |
| Organise pages | Yes | Pages copied in your order; rotation is metadata |
| Crop | Yes | The page boundary changes; content is hidden, not deleted |
| Sign | Mostly | An image is drawn on; the page beneath is untouched |
| OCR | Yes | An invisible text layer is added; pages are not rasterised |
| Fill a form | Yes | Field values are written in; flattening is optional and permanent |
| Add page numbers | Mostly | Text is drawn on; the page beneath is untouched |
| Add watermark | Mostly | Text is drawn on; the page beneath is untouched |
| Compress — Target size | No | Pages become images; the text layer is lost |
| PDF to images | No | Pages become pixels; not reversible |
| Images to PDF | No | Images are re-encoded as JPEG |
| Scan to PDF | No | Camera photographs are encoded as JPEG |
| Compress an image | No | Re-encoded as JPEG at a lower quality |
Always keep your original. The lossy operations cannot be undone by running them backwards — converting an image back to a PDF does not restore the text that rendering destroyed.
What is not here, and why
Everything on this site runs in your browser. That rules out a category of tools other sites offer, and it is worth being straight about which:
- PDF to Word, Excel or PowerPoint. Reconstructing an editable document needs layout analysis that is not practical in a browser tab. Any site offering it is uploading your file to a server.
- Password protection and unlocking. The library used here does not implement PDF encryption. Removing protection from documents is also not something this site wants to help with.
- Editing text. PDF was designed as a final format; genuine text editing means rebuilding the document.
The trade is deliberate: fewer tools, but your documents never leave your device. For a passport scan or a bank statement that is the better bargain.
