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 WebP to PNG 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 WebP to PNG reduce quality?

PNG 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 WebP images and download them all as PNG. The REST API also accepts individual files for automated batch workflows.

How do I convert WebP to PNG without software?

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

About WebP and PNG

WebP (source)

WebP is a modern format developed by Google. It is 25–35% smaller than JPEG or PNG at equivalent quality and is supported by all modern browsers.

PNG (output)

PNG is a lossless raster format that supports transparency. Ideal for graphics, logos, and screenshots where pixel-perfect quality matters.

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