Why convert JPEG to PNG?
PNG is lossless, so converting from JPEG won't compound any quality loss on future edits — though it can't restore detail JPEG's lossy compression already discarded. The main reason to convert JPEG to PNG is compatibility: PNG opens in every browser, image viewer and design tool without a plugin, while JPEG doesn't always. If you're sharing a file with someone else, sending it to a tool that expects a specific format, or archiving it for the long term, PNG is usually the safer target.

Common reasons to convert JPEG to PNG
- Uploading to a website builder, ad network or CMS that only accepts PNG
- Shrinking page load time with a more compressible file than the JPEG original
- Moving to a format that won't compound further quality loss if you plan to keep editing
Your file, handled carefully
Uploads use TLS in transit and AES-256 SSE-S3 at rest in production (when the production S3 credential gate is enabled), are processed in an isolated job, and deleted on the schedule you choose — as fast as immediately. We don't index, search, or share files between accounts. Read the full security model →
Frequently asked questions
Is converting JPEG to PNG free?
Yes — the Free plan includes 50 conversions every month, including JPEG to PNG. Paid plans raise that limit.
Will I lose quality converting JPEG to PNG?
PNG is lossless raster format with alpha transparency, ideal for graphics and screenshots. We use the highest-quality encoder settings by default so visual or data loss is minimized.
Do you keep a copy of my file?
Files are deleted automatically based on your plan's retention options. Free accounts can keep results for 1h or 24h; Pro and above add options such as delete-immediately and 7 days.
What is JPEG?
Compressed photographic format, the web's default for photos.
Will my converted file have a watermark?
On the Free plan, PNG output includes a small "Converted with Convyx" mark. Pro ($9/mo) removes it, along with the 25 MB file size cap.
What happens if a conversion fails?
You get a clear error message and the job is marked failed in your history — we never silently drop a file. Retry is one click. Monthly quotas count attempts (including failures) because processing starts as soon as the job is created.
