Frequently asked questions
Which output format should I choose?
Use JPG for photos that must open anywhere, PNG for screenshots, logos and images with transparency, WebP for websites where small files matter, and AVIF when you want the smallest files and only need to display them in modern browsers.
Are my images uploaded to a server?
No. Conversion runs in your browser using WebAssembly, so your images stay on your device. There is no account, no watermark and no cost.
Why did my transparent PNG get a white background?
You converted it to JPG, which cannot store transparency, so transparent areas are filled with white. Convert to PNG, WebP or AVIF to keep a transparent background.
Can I convert an animated GIF or WebP?
You can, but you will get a still image of the first frame. The converter does not output animations.
Is there a limit on how many images I can convert?
There is no set count. Each image can be up to 50 megapixels. The practical limit for a big batch is your device's memory, so very large batches on older phones may be better done in groups.
Why does converting to AVIF take longer?
AVIF encoding does much more work to produce small files, and it runs on your device. Large photos can take several seconds each. Other formats finish almost immediately.
About Image Converter
This converter reads JPG, PNG, WebP, AVIF, HEIC, GIF, BMP, TIFF and SVG files and writes JPG, PNG, WebP, AVIF or ICO, or combines a batch into one PDF with an image on each page. It recognizes each input by looking at the contents of the file rather than its extension, so a PNG that someone renamed to .jpg is still handled correctly. Images up to 50 megapixels are supported, which covers the photos from current phones and most cameras.

All of the work happens inside your browser, using the same kinds of image codecs desktop software uses, compiled to WebAssembly. Your files are never sent to a server, which makes conversion private and means there is no upload wait and no file-size cap set by a service. Multiple images are processed in parallel in background threads, so a large batch does not freeze the page, and you can download the whole set as a single zip.
Picking an output format comes down to where the image is going. JPG is the safe choice for photographs and works everywhere. PNG is lossless and keeps transparency, which makes it the right choice for screenshots, logos and anything you plan to edit. WebP gives smaller files than both and also keeps transparency, and every current browser displays it. AVIF is smaller still, but encoding is slower and some programs cannot open it yet. ICO is for favicons and Windows icons, with several sizes in one file.
A few things change in every conversion. Metadata such as camera details and GPS location is removed, though photo orientation is applied first so pictures stay upright. Converting to JPG fills transparent areas with white because JPG cannot store transparency. Animated GIF and WebP files convert to a still image of their first frame, a HEIC file with several images uses the primary one, and SVG graphics are rasterized at the size written in the file. Converting between two lossy formats compresses the image again, so work from the original when you can.
