How to convert images
- Add your images: HEIC, HEIF, PNG, JPG, WebP, GIF, BMP or AVIF.
- Choose the format you need. Formats your browser cannot create are greyed out.
- Set the quality (for JPG, WebP and AVIF) and what to do with transparent areas when converting to JPG.
- Click Convert images and download them one by one or as a ZIP.
HEIC to JPG: the most common conversion
iPhones and iPads save photos as HEIC to save space. Many websites, Windows apps and printing services still do not accept it. Converting to JPG makes your photos open everywhere. PDF Free decodes HEIC directly in your browser, so private photos are never uploaded.
Which format to choose
| Format | Best for | Transparency |
|---|---|---|
| JPG | Photos, sharing, printing | No |
| PNG | Logos, screenshots, text, graphics | Yes |
| WebP | Websites: 25–35% smaller than JPG | Yes |
| AVIF | Smallest web images (newer browsers) | Yes |
Example: a logo for a website
Your logo is a 900 KB PNG with a transparent background. Converting to WebP at 90% keeps the transparency and drops the size to around 60–120 KB, so your site loads faster.
What happens to transparency?
JPG cannot store transparent areas. When converting a transparent PNG or WebP to JPG, choose to fill those areas with white or black. PNG, WebP and AVIF keep transparency.
Frequently asked questions
Does converting reduce quality?
Converting to PNG is lossless. JPG, WebP and AVIF use the quality you choose; 90% looks identical to the original for almost all photos.
Why is AVIF greyed out?
Your browser cannot create AVIF files yet. Choose WebP, which is supported everywhere and almost as small.
Are animated GIFs supported?
Only the first frame is converted. The result is a still image.
Are my photos uploaded?
No. Conversion runs entirely on your device.
