Merge, split and shrink PDFs and images — all in the browser, nothing uploaded.
Combine multiple PDF files into one, in your browser.
Pull specific pages out of a PDF into a new file.
Shrink an image's file size or resize it, in your browser.
Combine PDFs into one file, pull specific pages out into a new one, or compress and resize an image before you send it. Every operation runs locally using the browser's own PDF and canvas APIs — your files never leave your device.
The most common surprise here is an image getting bigger after "compression": that's what happens when you convert a photo to PNG. PNG is lossless and right for screenshots and flat graphics; for photos, JPEG or WebP is the format that actually shrinks the file.
