Reduce PDF size without losing a single detail

Text, fonts, and vectors stay untouched

When you reduce PDF size here, only embedded image resolution gets optimized. Text, fonts, vector graphics, hyperlinks, and form fields remain identical. You can compress a PDF without losing quality on anything that matters.

Image-heavy reports see the biggest reduction in file size. Text-heavy documents barely change visually. Either way, your compressed PDF looks the same in any viewer and prints the same on any printer.

Shrink PDF file size for email, uploads, and forms

Email attachments

Most providers reject files over 25 MB. Reduce file size on your PDF before attaching. It actually goes through.

Upload forms and portals

Government applications, job portals, and legal submissions often cap uploads at 2 MB or 5 MB. Decrease the PDF file size to fit.

Scanned documents

A 20-page scan can hit 50 MB. Shrink the PDF file size down to a few megabytes without losing legibility.

Cloud storage

PDFs add up fast. Make PDF smaller before archiving and save real storage space across Google Drive, Dropbox, and OneDrive.

Compress any PDF file size by up to 80%

Scanned documents

60–80%

Scans are essentially full-page images, so the compressor has the most to work with. Contracts, receipts, signed forms all shrink dramatically.

Reports and presentations

40–60%

Charts, photos, and embedded graphics compress well. Text and tables stay untouched. The file size drops, the content stays the same.

Text-heavy documents

10–20%

Already compact by nature. The compressor cleans up internal structure and metadata without any visible changes to your PDF.

Zipping wraps the file in an archive. The PDF inside stays the same size when extracted. Compressing actually reduces the PDF internally, so the file itself is permanently smaller everywhere it goes: in email, on upload forms, in cloud storage.
