Is my image uploaded to a server?

No. All conversion happens entirely in your browser using the Canvas API and WebCodecs. Your images never leave your device.

What formats are supported?

Input: JPEG, PNG, WebP, AVIF, BMP, ICO, SVG, TIFF, HEIC, and JPEG XL. Output: JPEG, PNG, WebP (Chromium/Firefox), AVIF (Chromium/Firefox), ICO, TIFF, and JPEG XL. TIFF, HEIC, and JXL support requires clicking 'Load Advanced Codecs' in the Capabilities panel — they load on demand via WebAssembly.

What is the difference between the conversion modes?

Single Format converts all files to the same output format. Per-File lets you pick a different format for each image. Profiles lets you define multiple named configurations (e.g. Web, Thumbnail, Print) and assign images to them.

Can I convert multiple images at once?

Yes. Drop any number of images or paste from clipboard. All modes support batch processing, and you can apply per-file overrides after the batch is processed.

How does alpha (transparency) handling work?

JPEG does not support transparency. If you convert a PNG or WebP with an alpha channel to JPEG, the tool lets you choose a background fill color (default white) to flatten transparency. WebP, AVIF, and PNG preserve alpha by default.

Can I resize images during conversion?

Yes. In the Conversion Settings panel you can set a maximum width and/or height. The tool keeps the aspect ratio and never upscales beyond the original dimensions by default.

Does conversion remove EXIF/metadata?

Yes, by default. Re-encoding through the Canvas API strips EXIF, IPTC, and XMP metadata. This is a privacy feature. You can review the strip-metadata toggle in the Naming step.
