Compress PDF
Make your PDF smaller in seconds — for email, uploads or job applications. Everything runs in your browser, so your file never leaves your device.
Use lossless optimization for text PDFs (your text stays selectable), or scan mode to shrink scanned and image-heavy PDFs the most.
How it works
Choose a method
Lossless keeps text selectable; scan mode gives the smallest size for scans.
Add your PDF
Drag and drop or pick a file — it stays on your device.
Compress and download
Get your smaller PDF instantly. If it can't get smaller, we keep the original.
Drag a PDF here or choose a file
Everything runs in your browser — your file is never uploaded. Lossless means the PDF is only packed more efficiently internally; the content and text stay unchanged and selectable.
FAQ
Is it really free?
Yes. Compressing PDFs is completely free, with no sign-up and no watermark.
Do you upload my file?
No. Everything runs in your browser — your PDF never leaves your device.
Will my text stay selectable?
With lossless optimization, yes. Scan mode turns each page into an image, so text is no longer selectable — use it only for scanned or image-heavy PDFs.
Why didn't my PDF get smaller?
It may already be optimized. Lossless can't shrink an already-compact file; for scans, try scan mode for a much smaller result.
