Convert images any way
Drop up to 500 images, pick a format, then press the button. Change between JPG, PNG, WebP, AVIF, BMP and GIF, turn iPhone HEIC into anything, resize, rename and even hit an exact file size. Nothing is uploaded.
Files are processed in your browser and never uploaded.
How to use Convert images any way
Add your files
Drop up to 500 image, HEIC, HEIF or AVIF files onto the upload area, or tap the area to choose them from your device.
Set the options
Choose Quality, Resize, Longest, No enlarge, Target size and Max. Every setting is on screen before you add a file, so you can see what the tool will do before it runs.
Run it and save
Press Process it, Don →. The button stays disabled until there is something to work on, and each file shows its own progress and result. Press Download all, Don (.zip). Each finished file keeps a name based on the one you started with, so you can tell the versions apart.
What this tool does
Convert up to 500 images at once
Drop up to 500 images and the whole batch is converted in turn, each one with its own progress and result.
Save as PNG, JPEG, WebP, BMP or GIF, plus AVIF where supported
Save as PNG, JPEG, WebP, BMP or GIF, and AVIF as well on browsers that can encode it.
Convert HEIC and HEIF photos from iPhones
HEIC and HEIF photos straight off an iPhone are decoded here, which is the usual reason a photo will not open on a Windows machine.
Wide input support including GIF, BMP, TIFF, AVIF and SVG
Input covers JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, HEIC and SVG, so you rarely have to convert something before converting it.
Adjustable quality for lossy formats
The quality slider applies to JPEG, WebP and AVIF, so you can trade sharpness against size deliberately.
Resize by longest side, width, height, percentage or fit box
Resize by longest side, width, height or percentage while converting, with No enlarge to stop a small image being blown up.
Frequently asked questions
Can it convert 100 images at once?
Yes, up to 500 per batch. Everything runs on your device, so a big batch depends on your computer's memory and speed. On older phones or low-memory devices, very large or very many images may slow down, so just do them in smaller groups.
Are my images uploaded anywhere?
No. Everything happens inside your browser, so your files never leave your device and nothing is sent to a server.
Which formats can I convert between?
Save to PNG, JPEG, WebP, BMP and GIF, plus AVIF when your browser supports it. Inputs include JPG, PNG, WebP, GIF, BMP, TIFF, AVIF and SVG, plus HEIC and HEIF from iPhones. For HEIC and for GIF output a small helper loads automatically the first time you need it.
What happens to transparency when I save as JPEG, BMP or GIF?
Those formats are filled onto the background colour (white by default) because JPEG and BMP have no transparency and GIF support is kept simple here. PNG and WebP keep transparency. You can also tick Flatten to add a background on purpose.
Can it hit an exact file size, like 300 KB?
Yes. Tick Target size and set the KB. For JPEG, WebP and AVIF it searches the quality to fit under your target, and for any format it can also shrink the dimensions until it fits. Handy for forms and uploads with strict limits.
Will converting lose quality?
PNG and BMP are lossless. JPEG, WebP and AVIF use the quality slider, trading a little detail for much smaller files. GIF is limited to 256 colours, so photos may look posterised, while logos and flat graphics stay crisp.
