Supported formats at a glance

Format Best for Transparency Typical compression
PNG UI assets, icons, screenshots ✔️ Lossless
JPEG Photos, artwork with gradients Lossy (quality slider)
WebP Web delivery, mixed graphics ✔️ Lossy or lossless
AVIF Modern browsers, maximum savings ✔️ Advanced lossy compression

The tool first checks which formats your browser can export. If a format is missing from the dropdown it means the current environment cannot produce it via Canvas APIs.

Step-by-step

  1. Drag a file into the upload card or click to pick one. Most bitmap formats load correctly.
  2. Choose the Target format from the dropdown.
  3. Adjust the Quality slider whenever the selected format is lossy (JPEG/WebP/AVIF). Start around 80–90% for photos.
  4. Decide how to treat transparency. Keep alpha pixels or toggle the checkbox and pick a solid colour to flatten the background.
  5. Click Convert image. The result panel shows the new size, name and format before you download.
  6. Use Download image to save the file or Copy as Data URL to paste the converted asset straight into design, CSS or JSON.

🚀 Use Cases for PNG/JPG/WebP/AVIF Conversion

1. WebP/AVIF Transparency Optimisation

Convert transparent PNG icons to WebP or AVIF while keeping alpha so CSS sprites and design systems stay crisp.

2. Marketplace Listing Compression

Export JPEG product photos as WebP to meet Shopify, Etsy or Amazon asset requirements without re-uploading giant files.

3. Email & Document Delivery Workflows

Flatten background colours and down-convert to JPEG for newsletters and slide decks that enforce strict attachment limits.

4. Front-end Development Pipelines

Copy the Data URL directly into Storybook, Tailwind config or React components when experimenting with theme assets.

Tips & best practices

  • PNG ignores the quality slider because the export is always lossless. Use WebP or AVIF if you need smaller files.
  • AVIF provides exceptional compression but older browsers may not recognise it. Offer WebP or JPEG fallbacks when targeting legacy clients.
  • Converting from a lossy source (e.g., JPEG ➜ PNG) cannot restore lost detail; it only changes the container.
  • Background fill also applies when converting animated GIFs or PNGs to JPEG/WebP/AVIF—pick a colour that matches your layout.
  • Large files and high-resolution photos can take a few seconds; stay on the tab until the preview appears.

FAQ

Why do some formats disappear from the list?
The app probes browser support with canvas.toDataURL. Unsupported MIME types, such as AVIF on older Safari, are hidden to avoid failed downloads.

Can I add more formats (ICO, HEIC, TIFF)?
Browser Canvas does not export those MIME types natively. Consider using dedicated WebAssembly codecs (e.g., Squoosh, libheif) or server-side conversion if you need additional formats.

Is there a file size limit?
The only limit is the available memory in your browser. Extremely large files (e.g., 100 MP photos) may fail on low-powered devices. If that happens, resize the image first or use the Image Compressor tool.
