Do you upload my images to a server?

Yes — the image is sent to PicPerf's conversion service, converted, and returned to you as a download. It's processed only for the conversion and never stored.

Will I lose quality or transparency?

Switching to JPEG is lossy; PNG and WebP preserve transparency and can be lossless. AVIF decodes preserve color and transparency. JPEG XL conversions from JPEG are lossless and reversible — you get the exact original bytes back if you convert back. All tools default to the highest quality setting.

Is there a file size or count limit?

No account or queue. Convert one image at a time, free. There is no artificial size cap — very large files simply take longer to upload and convert.

How is this different from PicPerf's image CDN?

These converters are free, single-file tools that process one image at a time. PicPerf Images and PicPerf Turbulence optimize whole sites automatically — AVIF/WebP when smaller, resizing, and edge caching — without manual conversions. Use the converters for a one-off file; use PicPerf when you want it automated at the edge.

Free image converters: pick the format you have and the format you need. Each tool converts a single file on PicPerf's conversion service — no queue, no account. Files are processed only for the conversion and never stored, and conversions use the highest quality settings with transparency and animation preserved where the format supports it.

Doing this a lot? Right-click save with the PicPerf Image Saver instead of uploading each file.

Looking to automate this for a whole site? PicPerf Images converts to AVIF/WebP only when smaller and Turbulence does it at the edge for every HTML page — no code changes.
