Convert images to the format you need
Different jobs need different image formats. A website wants small, fast files like WebP or AVIF. A print shop or an old app may need PNG or JPG. This free image converter changes your pictures from one format to another in seconds, and it works right in your browser so your files never get uploaded.
How do you use the image converter?
- Add your images. Drag and drop them or click to browse your files.
- Pick a format. Choose AVIF, WebP, PNG, JPG, JPEG, or BMP.
- Set the quality. For lossy formats, slide to balance size and detail.
- Convert and download. Save each file, or download them all at once.
Which image format should you choose?
- WebP. Small files with wide support. A great default for the web.
- AVIF. Usually the smallest files at the same quality. Best for modern sites.
- PNG. Lossless with transparency. Good for logos, icons, and screenshots.
- JPG / JPEG. Universal for photos. Small files, no transparency.
- BMP. Uncompressed and very compatible, but large.
Why does conversion happen in the browser?
Your browser already knows how to decode and encode common image formats, so there is no need to send anything to a server. The tool draws your image onto a canvas and re-saves it in the new format. This keeps private photos private, removes upload and download waits, and lets you convert as many images as you like for free.
A note on HEIC and AVIF support
Browsers cannot save files in HEIC, so HEIC is offered as an input only, and only when your browser can read it. AVIF output works in most current browsers but not all. To be honest about what your device can do, the tool checks support and hides any format your browser cannot create. If a format is missing from the list, switching to a different browser may help.
Frequently asked questions
How do I convert an image to another format?
Drag your images onto the drop zone or click to pick files. Choose the output format you want, such as WebP, AVIF, PNG, JPG, or BMP, set the quality if it applies, then press Convert. Each image is processed in your browser and you can download the results one by one or all at once.
Which formats can this image converter output?
It can convert to PNG, JPG, JPEG, WebP, AVIF, and BMP. PNG, JPG, and WebP work in every modern browser. AVIF and BMP depend on your browser, so the tool checks support and only offers formats your browser can actually create. If a format is greyed out, your browser cannot encode it.
Can it convert HEIC images from my iPhone?
It can open and convert HEIC photos only if your browser is able to decode HEIC, which Safari on Apple devices can do. Browsers cannot save files as HEIC, so HEIC is supported as an input where possible, not as an output. To share an iPhone photo widely, convert it to JPG or WebP.
Is my image uploaded to a server?
No. The conversion runs entirely in your browser using the canvas in your device. Your photos are never uploaded, stored, or sent anywhere. That keeps private images private and makes the tool fast, since there is no upload or download wait.
What does the quality slider do?
For lossy formats like JPG, WebP, and AVIF, the quality slider controls the balance between file size and detail. A higher value keeps more detail but makes a bigger file. A lower value shrinks the file but can add blur or blockiness. PNG and BMP are lossless, so the slider does not apply to them.
Why convert to WebP or AVIF?
WebP and AVIF are modern formats that usually produce much smaller files than JPG or PNG at the same visual quality. Smaller images load faster on websites and use less storage. AVIF tends to compress the best, while WebP has the widest support, so both are good choices for the web.
Can I convert many images at once?
Yes. You can add several images and convert them together in one batch. Each result shows its new size so you can see how much space you saved. You can download each file separately or grab them all with the download all button.
