Why convert this way?
Every image format trades off differently between quality, transparency support, and file size. The right format depends on where the image is going — web, print, or an app icon.
How Fyleon does it
Fyleon decodes and re-encodes images using WebAssembly image codecs running locally, so even batches of photos never leave your device for files under 400MB. For files under 400MB, nothing is uploaded anywhere; the file never leaves your computer. Larger files route through Fyleon's dedicated cloud pipeline, billed against your plan's own monthly quota before any one-time charge applies.
Step-by-step
- Open the Convert Image tool and sign in (or create a free account — it takes a few seconds).
- Drop one or more image files onto the upload area, or click to browse for them.
- Choose your target format.
- Download the converted file(s) directly to your device.
A note on this conversion
Converting from a lossy format (like JPG) to another format can't recover detail that was already lost in the original compression — the new file will be clean, but not sharper than its source.
Files processed locally never touch Fyleon's servers, so a file with sensitive or confidential content never leaves your device.
