Convert an image format

Which format should you choose?

Format	Best for	Transparency	Trade-off
JPG	Photos; forms, portals and older software that accept nothing else	No — transparent areas become white	Lossy: tiny quality cost, big size savings
PNG	Screenshots, logos, graphics with sharp edges or transparency	Yes	Lossless, but photo files are often several times larger
WebP	Websites and modern apps; smallest files at the same dimensions	Yes	Not accepted by some older software and a few portals

How to convert an image

Choose your image — drop it above or click to browse.
Pick the target format and a quality level (for JPG and WebP; PNG ignores quality because it is lossless).
Convert and compare — the result panel shows the original and converted sizes side by side before you download.

Honest notes

Converting to PNG often makes the file bigger. PNG is lossless; that is the correct result, not an error, and the tool tells you when it happens.
Converting cannot add quality. A JPG saved at low quality will not become sharper as a PNG — the information is already gone. PNG only preserves what is there.
Animated images are converted from their first frame.
Popular one-step conversions have their own pages: JPG to WebP, PNG to WebP and WebP to JPG.

Privacy

Conversion runs 100% locally in your browser using its built-in image technology. Your image is never uploaded to ImageConvertPro or any other server, and nothing about the file is stored. The downloaded file always has the correct extension and type for the format you chose.

Frequently asked questions

Does converting change the dimensions?

No — the pixel dimensions stay identical. To change dimensions as well, use the image resizer; to hit a file-size limit, use the KB compressor.

Why does my converted file have a different size than expected?

Formats compress differently. JPG and WebP discard some detail to shrink files; PNG keeps every pixel. The result panel always shows both real sizes so there are no surprises.

Can I convert an iPhone HEIC photo here?

Only if your browser can open HEIC (Safari can; Chrome currently cannot). If the file cannot be read, the tool says so and suggests exporting the photo as JPG from the Photos app first.
