Frequently asked questions
Quick answers about converting images with PurePDF.
Is the JPEG to PNG converter really free?
PNG exports are always free on PurePDF. No usage caps, no watermarks, and no account required.
What are the file size limits?
Each image can be up to 20MB. This keeps conversions fast while still supporting high-resolution graphics and photography.
How do you protect my files?
Uploads travel directly to our Sharp-powered Node runtime, process in memory, and are deleted automatically after the download finishes.
Will image quality drop during conversion?
PurePDF tunes Sharp conversion quality for each format: JPG/JPEG exports land in the 70–85 quality range, WEBP targets 70–80, and PNG uses compression level 9 without touching pixel data. That balance keeps files lightweight while retaining the crisp detail your audience expects.
