Compress PDF

Smaller PDFs, without wrecking them

Big PDFs bounce off email limits, upload slowly, and eat storage — usually because of high-resolution images or scanned pages saved at far more detail than anyone needs on screen. HivePDF's compressor targets exactly that: it looks at each page and re-encodes the images, keeping the parts that matter. The result is a much smaller file, produced entirely in your browser, with no watermark and no account.

Why your text stays selectable

Many compressors flatten every page into a picture, which destroys selectable text and accessibility. HivePDF classifies each page first. A page with real text keeps that text — only its embedded images are downscaled and re-encoded. A scanned page is re-encoded as an image at a sensible resolution. Pages that are pure text are left alone. Your document's outline, links, and form fields survive the process.

Levels and honesty

Choose High quality to barely touch it, Recommended for a strong balance, or Small file to squeeze hardest. We never hand back a file that ended up larger than the original — if a PDF is already lean, we say so instead of pretending. Everything runs locally, so sensitive documents never leave your device.

What actually shrinks, and what doesn't

Compression works by finding redundancy — mostly in images — and re-encoding it more efficiently. A PDF made of vector graphics, plain text, or images that are already heavily compressed has little left to squeeze, so don't expect a big size change from files like that; the tool won't shrink them further just to show a number. The biggest drops come from scanned pages, screenshots, and photos saved at print resolution when they'll only ever be viewed on a screen.

When to reach for it

Compress before emailing, before uploading to a portal with a size cap, or before archiving years of scanned records where storage adds up. Do it after you've finished editing a document, not before — compressing, then merging or adding pages afterward, can leave inconsistent image quality across the file. If you need a guaranteed size rather than just "smaller," use one of the target-size versions instead of guessing at a quality level here.
