Best for scans & image-heavy files
Best for scanned documents and image-heavy PDFs. Text-based PDFs are already small — this tool won’t hand you a bigger or blurrier file.
Shrink big, scanned and image-heavy PDFs in your browser. Each page is re-encoded at a quality level you choose, with an optional grayscale mode for extra savings on scans — then rebuilt into a smaller file. Nothing is uploaded.
It is built for the PDFs that are actually large: photos, scanned contracts and image-based documents. Text-only PDFs are already tiny, so the tool leaves them untouched rather than making them worse.
No. Compression runs entirely on your device; the file never leaves your browser.
Text PDFs are already highly compressed. Rather than rasterizing them (which hurts quality and can grow the file), the tool keeps your original.
For image-heavy PDFs the pages are re-encoded as images, so text becomes part of the picture. Keep your original if you need selectable text.
