GIF Supports animation and transparency. Limited to 256 colors. Good for simple graphics.

AVIF Next-gen format. Excellent compression with high quality. Growing browser support.

💡 Tips

✅Use WEBP for web images — it's smaller and faster to load.
✅Use PNG when you need a transparent background.
✅Quality 80–90% is usually indistinguishable from 100% for photos.
✅Strip EXIF metadata to remove GPS location and camera info before sharing.
✅Batch convert multiple images at once to save time.
✅All processing is done locally — your images never leave your device.

❓ Frequently Asked Questions

Are my images uploaded to a server? ▼

No. All image conversion happens entirely in your browser using the HTML5 Canvas API. Your images are never sent to any server, stored in a database, or logged in any way. The entire process runs locally on your device.

Which format should I use for my website? ▼

For most web images, WEBP is the best choice — it offers 25–35% smaller file sizes compared to JPG and PNG while maintaining excellent quality. If you need transparency, WEBP also supports it. For older browser compatibility, JPG (photos) or PNG (graphics/logos) are safe fallbacks.

What is EXIF metadata and should I strip it? ▼

EXIF metadata is information embedded in image files by cameras and phones — including GPS coordinates, device model, date/time, and camera settings. If you're sharing images publicly, it's a good idea to strip this data to protect your privacy. The "Strip Metadata" option removes it during conversion.

What quality setting should I use? ▼

For most use cases, 80–90% quality is the sweet spot — it produces files that are visually indistinguishable from 100% quality but significantly smaller. Use 100% only when you need pixel-perfect accuracy (e.g. for print). For web thumbnails or previews, 60–75% is often sufficient.

Can I convert multiple images at once? ▼

Yes! You can upload as many images as you like and convert them all in one click. After conversion, use the "Download All" button to save all converted files at once, or download them individually using the download button next to each file.
