FAQ 常见时( Q)
Yes. No sign-up, no credit card. Free.ai gives every visitor 2,500 daily tokens — a single conversion costs about 200 tokens.
Drop your JPG file on the upload box, click Convert to PDF, then download the result. The conversion runs server-side in seconds.
100 MB per upload. For larger files, sign up for an account and use our async queue — files up to 1 GB process in the background and get emailed when done.
Both JPG and PDF are image formats. Pillow handles the conversion losslessly except where the target format itself is lossy (e.g. JPG).
Files are deleted from our server immediately after conversion. We do not retain, scan, or train on uploaded content. The download link is single-use and expires in 24 hours (7 days for signed-up users).
Yes. The conversion is a format change — we don't add a watermark, the output is yours to use anywhere, including commercial work.
No. Conversion runs entirely in your browser via our API — no software, no extensions, no plugins. Works on desktop, tablet, mobile.
Password-protected PDFs return a clear error pointing at /pdf/unlock/ — unlock there first, then re-upload here. Other format types don't support passwords.
Most conversions complete in 1-3 seconds. Large videos can take up to a minute. The progress bar updates in real-time.
Not on the public converter — but signed-up users can chain conversions in /workspace/ or write a 4-line script against our public API at api.free.ai/v1/convert/.
Yes — visit /convert/pdf-to-jpg/. The reverse-direction page handles it.
