Anyone facing a portal with a strict file-size cap
Why use Compress PDF?
- Targets the parts that actually take up space, re-encoding embedded raster images and removing unused objects.
- Leaves text untouched, because PDF text is stored as vector data that compression does not blur.
- Offers light, medium, and heavy levels so you can trade visible image quality against the smallest size.
- Displays before-and-after sizes immediately, so you know whether you cleared a 25 MB email limit.
- Compresses on your device, keeping contracts and financial documents off any third-party server.
Common use cases
- Shrink a report below the typical 25 MB email attachment limit before sending it.
- Optimize PDFs hosted on a website so visitors download them faster.
- Reduce the storage footprint of a large PDF archive in a cloud drive.
- Prepare an upload that fits inside a portal's strict file-size cap.

About Compress PDF
A PDF compressor reduces a file's size so it is easier to email, host, or store. This free tool works inside your browser and shrinks documents by re-encoding their embedded raster images and discarding unused objects, while leaving the actual text alone. That distinction is the key to understanding what compression can and cannot do. Text in a PDF is stored as vector glyphs backed by font data, not as pixels, so it is not re-compressed and never gets blurry. The savings come almost entirely from images: a scanned document or an image-heavy brochure can shrink considerably, whereas a plain text report with no pictures may barely change because it is already close to its minimum size. The tool gives you three levels. Light keeps images near-original and trims overhead, medium balances quality against size, and heavy pushes image quality down hardest for the smallest possible file. After processing, it shows the before-and-after sizes so you can immediately see whether you have cleared a target such as a 25 MB email limit. Common reasons to compress include fitting an attachment under a mailbox cap, speeding up downloads of a PDF hosted on a site, cutting cloud storage costs for a large archive, or squeezing a file under a strict upload limit. One caveat: a password-protected PDF must be unlocked first, because the tool cannot read encrypted page data. Because all of this runs locally with client-side libraries, sensitive contracts, financial statements, and legal files stay on your device and are never uploaded.
