Why Convert Image Formats?

Image format conversion is essential for web performance, compatibility, and storage optimization. Different formats serve different purposes:

  • Reduce file size — Converting PNG to WebP or AVIF can reduce file sizes by 25-50% without visible quality loss, making pages load faster.
  • Add transparency — Need transparency in your image? Convert JPEG to PNG or WebP to add an alpha channel.
  • Improve compatibility — Some systems don't support modern formats. Convert AVIF or WebP to JPEG or PNG for universal support.
  • Enable animation — Convert static images to GIF or animated WebP for simple animations and motion graphics.
  • Optimize for web — Modern formats like WebP and AVIF are designed specifically for web delivery with superior compression.
  • Convert iPhone photos — iPhones save photos in HEIC format by default. Convert HEIC to JPG or PNG for universal sharing and editing.

How Image Conversion Works

When you convert an image from one format to another, the converter decodes the source image into raw pixel data, then re-encodes it using the target format's compression algorithm. Here's what happens during conversion:

Lossy vs. Lossless Conversion

Lossy formats (JPEG, WebP lossy, AVIF lossy) discard some image data to achieve smaller file sizes. Each time you convert between lossy formats, you may lose additional quality — this is called generation loss. For best results, always convert from the original source file. Learn more in our guide to image compression.

Lossless formats (PNG, WebP lossless, GIF) preserve all image data. Converting between lossless formats maintains perfect quality, though file sizes may vary based on each format's compression efficiency.

What Gets Preserved

  • Pixel data — The actual image content is preserved (within the limits of the target format)
  • Dimensions — Width and height remain unchanged
  • Color profile — Most formats preserve ICC color profiles

What May Change

  • Transparency — JPEG doesn't support transparency, so alpha channels are flattened
  • Color depth — GIF is limited to 256 colors
  • Metadata — EXIF data may not transfer between all formats
  • Animation — Only GIF, WebP, and AVIF support animation

Best Format for Your Use Case

Photographs and Complex Images

Use WebP or AVIF for web, JPEG for universal compatibility.

These formats excel at compressing photographic content with millions of colors and smooth gradients.

Logos, Icons, and Graphics

Use SVG for vector graphics, PNG or WebP for raster graphics with transparency.

These formats preserve sharp edges and support transparency for overlaying on any background.

SVG best practices →

Screenshots and Text-Heavy Images

Use PNG for lossless quality, WebP lossless for smaller files.

Lossless compression prevents artifacts around text and UI elements.

Simple Animations

Use WebP or AVIF for smaller files, GIF for maximum compatibility.

Modern animated formats are 50-90% smaller than GIF while supporting more colors.

E-commerce Product Images

Use WebP with JPEG fallback, or AVIF for cutting-edge optimization.

Fast-loading product images directly impact conversion rates and SEO rankings.

Frequently Asked Questions

Is this image converter free?
Yes, completely free. No signup required, no watermarks, no limits on the number of conversions. Upload as many images as you need.
Can I convert HEIC to JPG?
HEIC (High Efficiency Image Container) is the default photo format on iPhones and iPads. While our browser-based converter doesn't yet support HEIC as an input format, you can easily convert HEIC to JPG using built-in tools on Mac (Preview) or Windows (Photos app). For a complete walkthrough of all methods, including free online converters and bulk conversion, see our HEIC/HEIF guide.
How do I convert PNG to JPG?
To convert PNG to JPG, simply upload your PNG file using the converter above, select JPEG as the output format, and click convert. The conversion happens instantly in your browser. Note that JPEG does not support transparency, so any transparent areas in your PNG will be filled with a white background. For photographs and complex images, converting from PNG to JPG can significantly reduce file size. You can also use our dedicated PNG to JPG converter page.
What's the maximum file size?
You can upload images up to 50MB. For larger files or batch processing, consider using a desktop tool or the Sirv API for programmatic access.
Are my images stored on your server?
Images are temporarily stored for processing and automatically deleted. We don't keep copies of your images or use them for any other purpose.
Which format should I convert to for websites?
WebP is the safest choice with 96% browser support and excellent compression. AVIF offers even better compression but has 92% support. Use JPEG as a fallback for older browsers.
Will converting my image reduce quality?
Converting to lossless formats (PNG, lossless WebP) preserves full quality. Converting to lossy formats (JPEG, lossy WebP, AVIF) may reduce quality slightly, but modern formats like WebP and AVIF maintain excellent visual quality even at high compression.
Can I convert multiple images at once?
This tool processes one image at a time. For batch conversion, check out Sirv's image CDN which automatically converts and optimizes images on-the-fly at scale.
What's the difference between WebP and AVIF?
Both are modern formats designed for the web. AVIF typically achieves 20-30% smaller files than WebP at the same quality, but takes longer to encode and has slightly lower browser support. WebP is the safer choice today; AVIF is the future. Read our detailed comparison →

Image Conversion Tips

Start with the highest quality source

Always convert from your original, highest-quality image. Converting a compressed JPEG to WebP won't recover lost quality — it will only compound the compression artifacts. If possible, start from RAW, TIFF, or high-quality PNG files.

Choose the right format for the content

Don't blindly convert everything to one format. Photographs compress well with lossy formats (WebP, AVIF, JPEG). Graphics with flat colors and text need lossless formats (PNG, lossless WebP) to avoid artifacts.

Consider your audience's browsers

Check browser support before committing to a format. WebP works in all modern browsers. AVIF is catching up but may not work for all users yet. When in doubt, provide fallbacks.

Test before deploying

Always visually compare converted images against originals at 100% zoom. Some images may show artifacts at certain compression levels that aren't visible in thumbnails.

Automate for production

For websites with many images, manual conversion doesn't scale. Use build tools, image CDNs like Sirv, or server-side processing to convert images automatically based on browser support.
