What is the maximum file size?

3 MB. This is set by the Vercel free tier request body limit. For larger images, use the API with a self-hosted instance — there is no size cap when self-hosted.

Does conversion affect image quality?

Lossless formats (PNG, TIFF) preserve every pixel exactly. Lossy formats (JPEG, WebP, AVIF) reduce file size by discarding perceptually insignificant detail. The quality slider controls this trade-off: 80 is a good default for web images, 90+ for print-quality exports, and 60–70 for thumbnails where small file size matters more than sharpness.

Why convert to WebP or AVIF?

WebP is 25–35% smaller than JPEG/PNG at equivalent quality and is supported by all modern browsers. AVIF is 50% smaller still but takes longer to encode and decode. Both formats support alpha transparency. Converting your images to WebP or AVIF before serving them from a website reduces page load times and bandwidth costs significantly.

Does PNG to WebP conversion lose transparency?

No. WebP supports full alpha channel transparency. Converting a PNG with a transparent background to WebP preserves the transparency. AVIF also supports alpha transparency. JPEG does not — converting a transparent PNG to JPEG replaces the transparent areas with white.

Can I convert SVG to PNG or JPEG?

Yes. SVG is accepted as an input format and can be rasterised (converted from vector to pixels) to any of the supported output formats. The output resolution depends on the SVG's viewBox and the browser's rendering. For high-resolution exports, use the API with a custom width parameter.

What quality setting should I use?

For JPEG: 85 for general use, 70 for thumbnails, 95 for high quality. For WebP: 80 for general use, 60–70 for thumbnails. For AVIF: 70 for general use (AVIF's perceived quality is higher than JPEG at the same numeric value). For lossless PNG and TIFF, quality is ignored.

Is it safe to convert AVIF to GIF in the browser?

Yes. The conversion runs entirely in your browser using the Canvas API — your images are not uploaded to any server. No data leaves your device.

Does converting AVIF to GIF reduce quality?

GIF is lossless, so no quality is lost in the conversion. The file may be larger than a lossy alternative.

Can I convert multiple files at once?

The web UI supports multiple files at once — drag and drop a batch of AVIF images and download them all as GIF. The REST API also accepts individual files for automated batch workflows.

How do I convert AVIF to GIF without software?

Use this tool — no installation required. Drag your AVIF file onto the converter, select GIF as the output format, and click Convert. The result downloads automatically.

AVIF to GIF Converter

Convert AVIF images to GIF format free, in your browser — no upload, no sign-up.

Why convert AVIF to GIF?

GIF preserves every pixel without quality loss, useful when you need a lossless archive copy of a AVIF image. GIF is often used as a target when you need wide compatibility — it is supported even in environments that do not accept WebP or AVIF.

–Legacy compatibility — GIF is supported in nearly every image viewer and email client, including ones that reject WebP.
–Batch conversion of AVIF files in a CI pipeline using the REST API: POST /api/image-converter.
–Quick one-off conversion without installing software — everything runs in your browser.

About AVIF and GIF

AVIF (source)

AVIF is based on the AV1 video codec and achieves up to 50% better compression than JPEG. It is supported by Chrome, Firefox, and Safari.

GIF (output)

GIF supports animation and transparency but is limited to 256 colours. Best for simple animations and pixel art.

Quality note: AVIF is lossy; GIF is lossless. Converting to GIF will not restore quality lost during the original AVIF compression, but no additional quality loss occurs in this conversion.
