Compress files

Compress PDF re-renders scanned pages at a lower resolution and rewrites pages with text without loss, so documents stay readable and their text selectable; Rasterise pages shrinks every page when size matters most. Compress image re-encodes photos at a quality level or to a target size in KB, and can cap their width. Compress Word & Office files shrinks .docx, .pptx and .xlsx files by recompressing the pictures inside them, keeping the format.

Every result shows the original size, the new size and the change, and says so when a file did not get smaller, so you can keep the original. All three run in your browser; only images your browser cannot open are decoded on our server. When a PDF must fit an upload limit, Split PDF can also cut it into parts below a maximum size.
