Why compress here instead
Honest about the trade-off
Standard and Strong aren't just two speeds of the same thing — they're genuinely different, and we tell you exactly what each one changes before you run it.
Built for scanned documents too
Strong mode's quality slider is designed for image-heavy and scanned PDFs, where the biggest size savings actually are.
Nothing uploaded
Compression runs in your browser. Your PDF never touches our servers.
Try again any time
Not happy with the result? Re-run with a different mode or quality level as many times as you like — nothing is destructive to your original file.
Questions about compressing PDFs
Standard cleans up and repackages the PDF's internal structure without touching its content — text stays fully selectable and searchable, but savings are typically modest. Strong renders every page as an image at a quality you choose, which can shrink scanned or image-heavy PDFs dramatically, but the resulting pages are no longer text-searchable or selectable.
Strong mode works by converting each page into a single image, the same way a scanner produces a PDF. That's what makes large size reductions possible on image-heavy files, but it means any text on the page is now part of a picture rather than real, selectable text.
Strong. Scanned PDFs are already just images of pages, so there's no searchable text to lose, and Strong mode's quality slider can shrink them significantly.
Start with Standard to preserve searchable text. If the file is still too large — usually because of large embedded images — switch to Strong, understanding that the text will no longer be selectable afterwards.
Not reliably. Password-protected or encrypted PDFs generally can't be processed in the browser — remove the password in your PDF reader first, then compress it here.
No. Compression runs entirely in your browser. Your files are never sent anywhere.
