What Is Image Format Conversion?
Image format conversion transforms images from one file format to another — for example, converting PNG to JPEG for smaller file sizes, or HEIC to JPG for broader compatibility. Each format has strengths: JPEG excels at photographs, PNG preserves transparency, WebP offers superior compression, and AVIF is the next-generation format with the best compression ratios. Convertilo uses WebAssembly codecs to convert between formats directly in your browser, preserving quality while optimizing for your target use case.
Image Format Comparison
Each image format has unique strengths. Choose the right format based on your needs:
| Format | Best For | Transparency | Animation | Compression | Browser Support |
|---|---|---|---|---|---|
| JPEG | Photographs, complex images | No | No | Lossy (up to 53%) | Universal |
| PNG | Graphics, screenshots, logos | Yes | No | Lossless/Lossy (up to 75%) | Universal |
| WebP | Web images, all-purpose | Yes | Yes | Both lossy and lossless | 95%+ browsers |
| AVIF | Maximum compression, modern web | Yes | Yes | Best ratio (up to 59%) | 90%+ browsers |
| GIF | Simple animations, memes | Limited (1-bit) | Yes | Lossy (up to 75%) | Universal |
| SVG | Icons, logos, vector graphics | Yes | CSS/JS | XML optimization (42%) | Universal |
Technology Behind Our Image Tools
Convertilo uses cutting-edge WebAssembly (WASM) technology to bring professional image processing directly to your browser. Instead of uploading files to a server, we run industry-standard codecs locally on your device:
MozJPEG — Mozilla's advanced JPEG encoder achieving up to 53% compression — the same technology used by major CDNs and image optimization services.
imagequant + OxiPNG — The combination of lossy quantization and lossless PNG optimization, reducing PNG files by up to 75% while maintaining visual quality.
libwebp — Google's WebP codec for encoding and decoding WebP images with support for both lossy and lossless compression.
libavif — The next-generation AVIF codec based on AV1, achieving up to 59% compression — the most efficient modern image format.
Gifsicle — Specialized GIF optimizer that preserves animation while reducing file size by up to 75% for static and 27% for animated GIFs.
SVGO — SVG optimization tool that parses and simplifies SVG markup, achieving 42% average size reduction through multipass processing.
All codecs are compiled to WebAssembly and run entirely in your browser — your images never leave your device.

Frequently Asked Questions About Conversion
Is quality preserved during format conversion?
Yes, we use optimal quality settings for each target format to maintain the best possible image quality during conversion.
What formats can be converted to JPG?
We support conversion from PNG, GIF, WebP, HEIC, SVG, PSD, TIFF, RAW and many other formats to JPG with optimal quality settings.
What happens to transparency when converting to JPG?
JPG doesn't support transparency, so transparent areas are replaced with white background. For transparency preservation, use PNG format.
Is batch conversion supported?
Yes, you can convert multiple files simultaneously. Our tool processes them efficiently while maintaining quality for each file.
Can I convert multiple files at once?
Yes, our batch conversion feature allows you to convert multiple files simultaneously, saving time and ensuring consistent quality across all conversions.
Can I adjust conversion quality settings?
Yes, you can adjust quality settings for each target format to achieve the perfect balance between file size and visual quality for your specific needs.
