Compress a PDF

No. Toolpit does not upload your file for processing — the tool runs as code in this browser tab, works on the copy your browser opened, and forgets it when you close the tab. You can check this yourself: open your browser’s network panel and run the tool. You will see the page, its scripts and the ads on the site, and — when you save, if you are signed in — one small request that charges 10 tokens to your account. None of them carries your file, its name or anything read from it, because file processing stays on your device.

"Compress PDF" means two different things. Lossless rewriting drops orphaned objects and packs the file more tightly — nothing degrades, and the saving is usually modest. Re-rendering turns each page into an image, which shrinks scan-heavy files dramatically but makes the text unselectable. Toolpit offers both rather than picking one and calling it magic.

A PDF that is mostly text is already small and highly compressed; there is little left to remove. Large PDFs are almost always large because of images, so if lossless mode gains you nothing, the size is in the pictures — try the re-render mode and lower the quality.

Toolpit adds no watermark or paid page quota. File and tool limits depend on device memory and supported features. Processing and previews are free; saving the result costs 10 tokens. A new account gets 50 tokens once its email is confirmed (once per email address) — five saves. Tokens pay for the download, never for a better version of it: the file you save is the same full-quality result either way.

Try "Keep everything" first: it rewrites the file more efficiently without touching the content, so text stays selectable and nothing is degraded. If the saving is not enough, the file is almost certainly full of images, and re-rendering the pages as pictures is what shrinks it — at the cost of turning text into part of the picture, so it can no longer be selected or searched.

Because it was already efficient. A PDF produced by a word processor is mostly text and fonts, which are tiny; there is little left to squeeze. The dramatic reductions come from scans and photo-heavy documents, where the images dominate the file size. If a mostly-text file is enormous, it usually has fonts embedded in full rather than subsetted.

No. Compression discards detail permanently, which is exactly how the file gets smaller. Always keep the original: compress a copy for sending, and archive the version you started with.
