What is this?

Image Converter is a free, browser-based tool that converts image files between popular formats — PNG, JPEG, WebP, AVIF, TIFF, and GIF. SVG files can also be rasterised to any of those formats. No software to install and no sign-up required.

How to use

  1. Upload: Click the file picker and select your image (up to 3 MB).
  2. Choose formats: Select the source format and your desired output format, then adjust quality if needed.
  3. Convert & download: Click Run. A preview appears immediately and you can download the converted file.

FAQ

What is the maximum file size?
3 MB. This is set by the Vercel free tier request body limit. For larger images, clone the repo and run locally — there is no size cap when self-hosted.
Does conversion affect image quality?
Lossless formats (PNG, TIFF) preserve every pixel. Lossy formats (JPEG, WebP, AVIF) use the quality slider — 80 is a good default that balances file size and visual fidelity.
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. Both are great for web delivery.

Why convert WebP to JPEG?

Note: WebP may contain transparent areas. Converting to JPEG replaces transparency with a white or black background since JPEG does not support an alpha channel.

  • Email attachments — JPEG files are universally supported and significantly smaller than PNG or TIFF, making them ideal for sharing photos by email.
  • Batch conversion of WebP 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 WebP and JPEG

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.

JPEG (output)

JPEG is a lossy format optimised for photographs. It achieves small file sizes at the cost of some quality loss, which is usually imperceptible.

Quality note: Both formats use lossy compression. Converting between them introduces a second round of compression, which can slightly reduce quality. Where possible, convert from the original lossless source rather than from a previously compressed file.

How to convert WebP to JPEG

  1. 1.Drag your WebP file (or files) onto the converter above, or click to browse.
  2. 2.Confirm the output format is set to JPEG. Adjust quality or size options if needed.
  3. 3.Click Convert. The conversion runs in your browser — your images are never uploaded.
  4. 4.Download the JPEG file. For multiple files, a ZIP is downloaded automatically.

Frequently asked questions

Is it safe to convert WebP to JPEG 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 JPEG reduce quality?
Converting to JPEG uses lossy compression, so some quality reduction is possible. The tool uses high-quality settings by default. For archival use, keep the original WebP file.
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 JPEG. The REST API also accepts individual files for automated batch workflows.
How do I convert WebP to JPEG without software?
Use this tool — no installation required. Drag your WebP file onto the converter, select JPEG as the output format, and click Convert. The result downloads automatically.
