One file or a whole batch
Compression runs on our server, so your files are uploaded. Each one is deleted as soon as your download finishes, and nothing is stored.
Most oversized PDFs are large because of the images inside them. Compression re-encodes those at a sensible resolution and strips out data nothing is using.
Drag files in or click to browse. Add several at a time if you have a batch to get through.
Press Compress and each file is processed in turn. The saving for every file is shown as it finishes.
Take the files individually or grab the whole batch as a ZIP. If a file did not shrink, just keep your original.
Usually a limit somewhere is the reason you are here.
Get a document under the cap most mail providers enforce so it actually sends.
Meet the size limit on an application or government portal that rejects large files.
Cut down a scan saved at far higher resolution than it needs for reading on screen.
Send a document through a chat app that struggles with large attachments.
Publish a brochure or guide that will not take an age to download.
Reduce a large archive of documents you need to keep but rarely open.
Compression trades detail for size. Knowing where the size actually comes from helps you decide.
What compression does to your file and where it goes.
Upload the file and it is compressed automatically. You see the original size, the new size and exactly how much came off before you download. No account and no watermark.
