Question 1

What image formats can I convert between?

Accepted Answer

You can convert between JPG/JPEG, PNG, WebP, and AVIF formats. We also support HEIC files from iPhones - when you upload a HEIC file, you can convert it to any of these standard formats. All conversions happen instantly in your browser with no uploads required.

Question 2

What's the difference between JPG, PNG, WebP, and AVIF?

Accepted Answer

JPG is the universal standard format, best for photos but doesn't support transparency. PNG is lossless and supports transparency, ideal for graphics and logos but creates larger files. WebP is a modern format that's 30-40% smaller than JPG while maintaining quality and supporting transparency. AVIF is the newest format, offering 50-60% smaller files than JPG with excellent quality, but may not work in older browsers.

Question 3

Can I convert iPhone HEIC photos to other formats?

Accepted Answer

Yes! Our tool fully supports HEIC (High Efficiency Image Format) used by iPhones. Simply upload your HEIC file and convert it to JPG, PNG, WebP, or AVIF. This is particularly useful for sharing iPhone photos with users on other platforms that don't support HEIC natively.

Question 4

Should I use quality settings when converting?

Accepted Answer

Quality settings are available for JPG, WebP, and AVIF formats. For most use cases, 90% quality (default) provides an excellent balance. Use 100% for archival or professional work, 80-90% for web use, and 60-80% for thumbnails or when file size is critical. PNG doesn't have quality settings as it's always lossless.

Question 5

When should I use each format?

Accepted Answer

Use JPG for photos that need universal compatibility. Use PNG for images with transparency, text, or when you need lossless quality. Use WebP for modern websites needing smaller files with good browser support. Use AVIF for the smallest possible files with the best quality, if your audience uses modern browsers (Chrome 90+, Firefox 93+, Safari 16+).

Question 6

Will converting formats reduce file size?

Accepted Answer

It depends on the conversion. Converting to WebP or AVIF typically reduces file size by 30-60% compared to JPG. Converting from JPG to PNG usually increases file size because PNG is lossless. Converting from PNG to JPG reduces size but loses transparency. The tool shows the size difference after conversion so you can decide whether to download it.

Question 7

Is conversion lossless or lossy?

Accepted Answer

PNG is always lossless - no quality is lost. JPG, WebP, and AVIF are lossy formats where you can control the quality-to-size trade-off with the quality slider. Converting from any format to PNG preserves quality completely. Converting from PNG to lossy formats (JPG, WebP, AVIF) will reduce quality slightly based on your quality setting.

Question 8

Do all browsers support WebP and AVIF?

Accepted Answer

WebP is supported by all modern browsers (Chrome, Firefox, Edge, Safari 14+, Opera) covering 97%+ of users. AVIF is newer with support in Chrome 90+, Firefox 93+, and Safari 16+, covering about 80-85% of users. If you need maximum compatibility, stick with JPG or PNG. For modern websites, WebP is a great choice. Use AVIF if your audience primarily uses the latest browsers.
