Convert images between formats
Convert images between formats
Image formats exist for different jobs: JPG compresses photos well, PNG handles graphics and transparency losslessly, GIF suits simple animations, WebP delivers modern web performance, and HEIC is Apple's efficient native format. Our converter switches any of these to any other — JPG, PNG, GIF, WebP, or HEIC — so files open correctly everywhere. Converting between lossless formats preserves quality completely, while converting to JPG may introduce slight compression artifacts, which is expected and often unnoticeable.
Conversion is one of the most common fixes for compatibility problems — a stubborn HEIC that will not upload, a PNG too heavy for email, a file a website refuses to accept. It is free, requires no account, and your image is deleted automatically after processing.
How to convert an image
- Upload your image
- Choose the output format: JPG, PNG, GIF, WebP, or HEIC
- Click Process to convert
- Download your converted image
Tips for best results
- Use PNG for graphics, logos, and transparency; JPG for photos.
- Convert HEIC to JPG for maximum device and platform compatibility.
- Use WebP when the image will be served on a website.
- Keep the original if you might need the source format later.
When should you convert an image?
Format conversion solves compatibility at every turn. Convert HEIC photos so older systems and upload forms accept them, turn PNGs into JPGs for lightweight email attachments, produce WebP assets for fast web pages, or export GIFs from stills for simple animations. Matching the format to the destination — email, web, print, or app — is the fastest way to make an image work everywhere.
What to know before you start
Lossless-to-lossless conversions (such as PNG to GIF) keep full quality; converting to JPG trades slight compression artifacts for much smaller files. The tool accepts JPG, PNG, GIF, WebP, and HEIC. Processing is private and free on first use — files are encrypted and deleted automatically.
