Large images may take longer to vectorize. For best results, consider resizing below 2 MP first.

How does the format converter work?
This tool uses your browser's built-in Canvas API to decode your image and re-encode it in the format you choose. For SVG output, a client-side vectorization library traces your image into vector paths. The entire process runs locally on your device — your images are never sent to any server.
Tips for Better Format Conversion
- Choose WebP for web delivery — WebP produces files 25–35% smaller than JPEG at the same visual quality, and it supports both lossy and lossless compression as well as transparency. All modern browsers support it, making it the best default choice for websites.
- Use PNG for transparency — If your image has transparent areas (logos, icons, overlays), convert to PNG. JPEG does not support transparency and will replace transparent pixels with a solid background color (usually white).
- Convert HEIC from iPhones — iPhones save photos in HEIC format by default, which many websites and Windows applications cannot open. Convert HEIC files to JPEG or WebP for universal compatibility across all devices and platforms.
- Try SVG vectorization presets — When converting raster images to SVG, experiment with the Posterized preset for flat-color illustrations, or the Detailed preset for complex artwork. Each preset produces dramatically different vector results.
- Adjust quality for the target format — When converting to JPEG or WebP, use the quality slider to balance file size and visual fidelity. A setting of 80–85% is ideal for most use cases. PNG is always lossless, so no quality slider is needed.
- Batch convert for efficiency — Drop multiple images at once to convert an entire folder in one operation. All files will be converted to your chosen format and can be downloaded together with the "Download All" button.
When to Convert Your Image Formats
- Optimizing images for websites — Convert JPEG and PNG files to WebP to reduce page load times by 25–35%. Faster sites rank higher in search results and provide a better user experience on mobile devices.
- Making iPhone photos compatible — Convert HEIC photos from your iPhone to JPEG or PNG so they can be opened on Windows, uploaded to any website, or shared with anyone regardless of their device.
- Creating logos and icons with transparency — Convert JPEG product photos to PNG when you need to remove the background and keep transparency for overlays, watermarks, or composite images.
- Preparing images for print — Convert WebP files (which some print shops cannot handle) to high-quality JPEG or PNG for reliable printing on any service.
- Vectorizing artwork — Convert raster logos, illustrations, or line art to SVG for infinitely scalable graphics that stay crisp at any size — perfect for responsive web design and print materials.
Frequently Asked Questions
Why convert image formats?
Different formats have different strengths. JPEG is best for photos (small size, universal support). PNG preserves transparency and is lossless. WebP offers the best compression-to-quality ratio and is supported by all modern browsers.
Can I convert multiple images at once?
Yes! You can select or drag & drop multiple images at once. They will all be converted to the format you choose. Use the "Download All" button to save them all at once.
What happens to transparency?
PNG and WebP support transparency. If you convert a transparent PNG to JPEG, the transparent areas will become white since JPEG does not support transparency. To preserve transparency, use PNG or WebP as your output format.
How does SVG vectorization work?
When you convert a raster image (JPG, PNG, WebP) to SVG, the tool traces the image into vector paths using different presets. You can choose from styles like Default, Posterized, Detailed, or Artistic. SVG files can also be converted to raster formats — the tool renders the SVG on a canvas and exports it as JPG, PNG, or WebP.
Does converting between formats reduce image quality?
Converting to a lossy format (JPEG, WebP) involves re-encoding, which can introduce slight quality loss — especially at lower quality settings. Converting to PNG is lossless and preserves all pixel data. For minimal quality loss, keep the quality slider at 85% or above when converting to JPEG or WebP.
Can I convert HEIC/HEIF photos from my iPhone?
HEIC/HEIF support depends on your browser and operating system. Safari on macOS and iOS can typically handle HEIC files natively. On Chrome or Firefox, HEIC support may be limited. If your browser can display the HEIC file, ImgLab can convert it to any supported output format.
Is WebP supported everywhere?
WebP is supported by all modern browsers including Chrome, Firefox, Safari (14.1+), and Edge. It is also supported on Android and iOS. The only environments where WebP may not work are very old browsers or legacy software. For maximum compatibility, JPEG remains the safest choice.
Does conversion preserve image metadata?
No — when ImgLab converts your image using the Canvas API, metadata such as EXIF, GPS coordinates, and camera information is stripped during re-encoding. This is actually a privacy benefit, as sensitive location data is automatically removed. If you need to inspect metadata before converting, use our Metadata Viewer tool first.
