Upload your PDF and tick what you want to fix: remove the blank pages scanners leave behind, crop the leftover white margins, make every page the same size (A4), or straighten sheets that came out crooked when scanned. Only what you tick is applied. If you choose to crop, unify or straighten, those pages are saved as an image, which is normal when fixing scans. Everything happens in your browser: the file is never uploaded to any server.

Preguntas frecuentes
Are my files uploaded to any server?
No. The whole process happens in your own browser, so your files never leave your device: they're not uploaded, not stored, and nobody sees them.
Is it free? Are there any limits?
Yes, it's free, with no watermarks and no sign-up. The free plan supports files up to 10 MB (and up to 5 at a time in the tools that combine several PDFs); MásPDF Pro removes those limits.
Why does text stop being selectable after cleaning?
It only happens if you crop, unify or straighten: to do it well, those pages are saved as an image. If you only remove blank pages, the text stays as it is.
Does straightening make the scan perfect?
It's an automatic aid, not magic: it corrects most typical scanner tilts, but in tricky cases it may end up slightly off. That's why we mark it as experimental.
