Komprimera PDF — frequently asked questions

Why did my file's text become blurry after compressing?+

Compression re-renders each page as an image and re-encodes it — it trades sharpness for file size, which is most noticeable on small text at the 'High' setting. Try 'Low' or 'Medium' first.

Will compression remove hyperlinks or form fields?+

Yes — because the page is flattened to an image, interactive elements like links and form fields won't survive compression.

Is this the same as a 'PDF size reducer'?+

Yes — compressing a PDF and reducing its file size are the same operation. This tool re-encodes the page images at your chosen quality level to shrink the total size.

Do you upload my files to a server?+

No — every tool here processes your files entirely on your device, and nothing is uploaded to a server. The AI tools that used to send extracted text to a server are currently disabled.

Is there a file size limit?+

There's no artificial limit we impose, but since processing happens in your browser, very large files (500+ MB or 1,000+ pages) are limited by your device's memory rather than by us.
