Choose filesSmaller PDFs, text still sharp
Most of a PDF's size comes from the photos and scans inside it. Localvert shrinks those images to a sensible resolution, recompresses them and tidies up the file's internal structure.
Text, vector graphics and links are left untouched, so they stay crisp and selectable.

Pick the right level
Recommended suits most documents and keeps photos clear on screen. Strong makes the smallest file for email attachments and upload limits. Light keeps print quality for documents you plan to print.
Frequently asked questions
How much smaller will my PDF get?
It depends on what's inside. Scanned documents and PDFs full of photos often shrink by 50–90%. PDFs that are mostly text are already small, so there may be little to remove — in that case you get your original back unchanged.
Are my files uploaded to a server?
No. Compression runs entirely in your browser with WebAssembly. Your document never leaves your device, which matters for contracts, statements and ID scans.
Will the text become blurry?
No. Only images are recompressed. Text and vector drawings are never turned into pictures.
