Compress PDF
Reduce PDF file size for email, uploads, and client delivery while keeping a result-first comparison before you download anything.

Compression Results
No PDF analyzed yet.
- Compression is file-dependent. Already optimized or image-heavy PDFs may not shrink much.
- If savings are minimal, you can skip the download and keep your original file.
Before you upload
- Works with one `.pdf` file at a time and keeps processing in your browser.
- Best results usually come from PDFs with duplicate structure or inefficient object streams.
- Image-heavy or already optimized PDFs may shrink only a little, or not at all.
What you get
You will see the original size, optimized size, and savings before deciding to download the output file.
Common use cases
- Prepare PDFs for email attachments and approval loops
- Reduce upload size for portals, forms, and client handoff systems
- Check whether a PDF can be made lighter before sending or archiving
Quick FAQ
- Will every PDF shrink a lot? No. Already optimized files or image-heavy exports may only change a little.
- Why show the result before download? Because some files are not worth replacing if the savings are too small.
- Is this a full PDF optimizer? No. It is a practical browser tool for lighter exports, not a complete document editing suite.
Before you send a PDF
Decide whether the job changes visible content, page order, or file size. Fill and sign before final compression, split before merging if only some pages are needed, and review the exported PDF before sending it to a client, portal, or archive.
PDF work often fails when the final destination is ignored. A portal may care about file size, an approval flow may care about signatures, and a handoff may care about page order. Work backward from that requirement and keep the final downloaded file separate from the original.
- Keep the source PDF until the export has been checked.
- Protected or damaged PDFs can fail even when the page loads normally.
- Compression should be the last step after pages and overlays are final.
After downloading the result, open it once before using it in a client send, upload form, website, or archive. This final check catches format support issues, unexpected file size changes, missing characters, clipped media, or page-order mistakes while the original file is still available.
If the output will be reused, note the settings that produced it. That makes the next export easier to repeat and reduces guesswork when another file needs the same treatment.
