Frequently Asked Questions
Which formats can I convert between?
Input: PNG, JPEG, WebP, GIF, BMP, AVIF, TIFF, ICO. Output: PNG, JPEG, WebP, and AVIF (when your browser supports AVIF encoding). Not all input formats support all output formats.
Does conversion reduce image quality?
PNG and WebP lossless modes preserve quality. JPEG, WebP lossy, and AVIF use compression that may reduce quality. Adjust the quality slider to balance file size and visual fidelity.
Can I convert multiple images at once?
Upload and convert images one at a time. For batch conversion of many files, dedicated desktop tools or command-line utilities like ImageMagick are more efficient.
Is my image uploaded to a server?
No. Conversion uses the browser Canvas API. Images are processed locally and never sent to Dokall servers.
Why is AVIF output not available?
AVIF encoding depends on browser support. Chrome and Firefox support AVIF export in recent versions. Safari added support in later releases. If AVIF is unavailable, use WebP as a modern alternative with wide support.
