About this conversion
PDFs balloon in size when they contain scans or high-resolution photos, which quickly runs you into email attachment limits and slow uploads. Compressing a PDF re-encodes those embedded images at a more sensible quality and resolution, often cutting the file by 50-90% while leaving the text perfectly crisp.
Most "compress PDF" services upload your document to do this — a real concern for anything private. Here the whole process runs in your browser, so your contracts, statements and scans never leave your device. Text-only PDFs are already efficient and won't shrink much; if nothing can be saved, you simply get your original file back.
Frequently Asked Questions
How much smaller will my PDF get?
It depends on what's inside. Scans and photo-heavy PDFs often shrink 50-90%. Text-only PDFs are already efficiently compressed and may barely change — if nothing can be saved, you get your original back untouched.
Does compression affect the text?
No — text, fonts and vector graphics are untouched and stay perfectly sharp. Only embedded photos/scans are re-encoded.
Is it safe for contracts and private documents?
Yes — this is the key difference from other PDF compressors: your document is processed entirely inside your browser and never uploaded anywhere.

Who we are — and what we refuse to do
We're a small team that got tired of "free" converters treating your files as the product.
So we built Converting Free the only way we'd trust ourselves: the whole toolbox — image, document and archive converters, compressors, time-zone and unit tools, calculators and text utilities — does its work on your device. Open your browser's network tab while you convert something; you'll watch nothing leave.
We don't run ads, we don't set tracking cookies, and we don't operate a server that stores files. That isn't a privacy-policy promise — it's how the site is engineered. There is simply nowhere for your data to go.
Why we built it
Search for "convert X to Y" and the top results usually want something from you before they'll lift a finger:
- —Your file, uploaded to a server you know nothing about
- —Your patience, spent on queues, captchas and "premium speed" upsells
- —Your data, harvested by the trackers stacked beneath the ads
We think a converter should be a tool, not a trade.
Ours takes nothing from you: no uploads, no accounts, no tracking.
