Up to 500 MB on a computer (Chrome/Edge, 8 GB+ RAM) · 150 MB on phones. No upload, no account, no daily cap.
Up to 500 MB on a computer with 8 GB+ memory, 150 MB on phones — no server, no upload cap.
File size limits on PDF compressors exist because compression on a server costs money. Every 100MB you upload consumes bandwidth, storage, and CPU time on the provider's infrastructure. To protect that infrastructure from abuse — and to push users toward paid plans — free tiers get capped at 25MB, 5MB, or 2 tasks per day.
PDFree eliminates this problem entirely: your file never leaves your browser. The compression algorithm runs in JavaScript on your device. There are no server costs to cover, so there is no daily limit and no upload cap — the only size limit protects your own device's memory.
The real limit: your device's memory. In Chrome or Edge on a computer with 8 GB+ RAM, PDFree accepts files up to 500 MB — an 800 MB scan worked in our tests at about 2 GB of browser memory, so 500 MB leaves room for your other tabs. Phones, Safari and Firefox don't report their memory, so they get a safe 150 MB. For big files, close other browser tabs first.
Gmail and Outlook limit attachments to 25MB. A 40MB scanned report won't go through. Compress it down to 8MB and send it without needing a cloud link.
Many e-filing systems cap uploads at 10MB or 20MB. Legal documents with scanned exhibits frequently run 50–200MB. Compress locally to stay under the portal's limit.
WhatsApp limits files to 100MB. A 180MB architectural drawing won't send. Compress it first, then share directly from your phone.
Merging five 80MB PDFs creates a 400MB file. Compress each one first, then merge them for a final document that's practical to store and share.

Open PDFree's PDF compressor, drop in your file and pick a compression level. It runs entirely in your browser and downloads the smaller file in seconds. No account, no upload, no daily limit — files up to 500 MB on a computer, 150 MB on phones, while most free online compressors cap uploads around 25MB.
Yes — up to 500 MB in Chrome or Edge on a computer with 8 GB+ memory, and up to 150 MB on phones, Safari and Firefox. Processing happens entirely in your browser, so the cap protects your device's memory rather than a server's bandwidth — a 500 MB scan took about 30 seconds on an 8 GB laptop in our tests.
iLovePDF processes files on their servers, creating real bandwidth and compute costs. PDFree processes files locally in your browser — there are no server costs, so there is no daily limit and no 25MB cap; files go up to 500 MB on a computer, limited only to protect your device's memory.
Results depend on the content. Image-heavy PDFs typically shrink 40–80%. Text-heavy PDFs compress 10–30%. PDFree uses the same compression algorithms as desktop tools.
No. Unlike SmallPDF (2 tasks/day free) or iLovePDF (daily limits), PDFree has no daily cap. Compress as many PDFs as you need, as often as you want.
No. PDFree never uploads your file. The entire compression operation runs in JavaScript inside your browser, on your device. Your document stays completely private — it never reaches any server.
