Your file never left your device. Not a byte.
Why this matters
Gmail caps attachments at 25MB. Outlook at 20MB. Most business PDFs with images sit between 8–30MB — right in the rejection zone. The usual advice is to upload your file to an online compressor, but that means sending your document to someone else’s server. If it’s a contract, financial statement, or anything with personal data, that’s a problem.
fwip compresses using WebAssembly in your browser. The file stays on your machine the entire time. No server. No cloud. No third party.
Frequently asked questions
What’s the maximum email attachment size for Gmail? 25MB. Outlook is 20MB. Yahoo is 25MB. If your compressed PDF is under 15MB, you’ll clear every major provider comfortably.
Does compressing a PDF reduce quality? It depends on the level. Medium (150dpi) preserves most visual quality — text stays sharp, images stay clear. Nano (72dpi) is aggressive and better suited for text-heavy documents where image quality isn’t critical.
Is it safe to compress PDFs online? Most online compressors upload your file to their servers for processing. Some delete it after an hour, some don’t say. fwip processes everything on your device. Your PDF never touches a server.
How much smaller will my PDF get? Typical reduction is 60–90%, depending on how many images the file contains. A 15MB PDF with photos often compresses to 2–4MB on Medium.
Can I compress multiple PDFs at once? In the browser, one at a time. With fwip’s desktop app, batch processing is included — drop a folder of PDFs and compress them all in one go.
