How do I convert an image to another format?
Choose or drag in one or more images, pick the format you want, PNG, JPG or WebP, and press Convert images. Download each file or all of them as a ZIP. There's no sign-up, and the conversion happens in your browser rather than on a server somewhere.
What's the difference between JPG, PNG and WebP?
JPG is small and good for photos but has no transparency. PNG is lossless and keeps transparency, so it suits logos and screenshots, though photos become large. WebP is a modern format that's usually smaller than both and also supports transparency. Pick based on where the image goes.
Why did transparent areas turn white?
JPG can't store transparency. When you convert a PNG or WebP with see-through areas to JPG, those areas are filled with white. Convert to PNG or WebP instead if you need to keep the transparent background, for example for a logo on a coloured website.
Can it convert HEIC photos from an iPhone?
Not yet, because browsers can't read HEIC files. On an iPhone, set Camera, Formats to Most Compatible so new photos save as JPG, or share the photo as JPG from the Photos app, then convert it here if you need another format. Android photos are usually JPG.
Is converting free and private?
Yes. It runs inside your browser, so files aren't uploaded and there's no limit besides your device's memory. That makes it safe for private pictures, such as scanned documents or family photos, and you don't need an account to use it. Nothing is stored afterwards.
Should I use WebP for my website?
Usually yes. WebP files are typically smaller than JPG or PNG at the same visible quality, so pages load faster on mobile data. All modern browsers support WebP. Keep a JPG copy if you also need to email or print the picture, where JPG is more universally accepted.
How do I convert PNG to JPG?
Choose the PNG files, pick JPG as the output and convert. Transparent areas become white, and the files usually get much smaller, especially for photos. For logos and screenshots with sharp text, PNG often looks better, so convert only when you need JPG. Check the white background looks right.
How do I convert WebP to JPG?
Choose the WebP images, pick JPG and convert. This is useful when a form or older app won't accept WebP, which is common with images saved from websites. The JPG files open everywhere, including older phones and office software. Quality stays close to the original WebP.
Can I convert GIF or BMP files?
Yes, GIF and BMP are accepted as inputs and can be saved as JPG, PNG or WebP. Animated GIFs become a single still image, because these output formats are saved as one frame here. BMP files usually shrink dramatically when converted. The first frame is used.
Does converting reduce quality?
Converting to PNG is lossless. Converting to JPG or WebP uses compression, so a little detail can be lost, though it's rarely visible at normal sizes. Keep your originals, and use Compress image if you want to control quality precisely. Most people won't notice any difference.
Can I convert many images at once?
Yes. Add several images, choose one output format, and convert them together. Download them one by one or as a single ZIP file. That's useful for converting a folder of product photos to WebP for an online store. Each file keeps its own name, with the new extension.
Does it work on a phone?
Yes, in modern mobile browsers. Pick images from your gallery, choose the format and download. It helps when a portal on your phone rejects a file type, for example insisting on JPG when your screenshot is a PNG. No app or account is needed for any of it.
Will the image size in pixels change?
No. Converting keeps the same width and height; only the file format and file size change. To change dimensions, use Resize image before or after converting. Converting and resizing together is a good way to make web images light. Only the format and file size change.
Why is my converted PNG bigger than the JPG?
Because PNG stores every pixel exactly, while JPG compresses photos heavily. Photos saved as PNG are often several times larger. PNG is worth it for graphics, logos and screenshots, but for photos JPG or WebP is the sensible choice. Try WebP for the smallest files.
Is there a file limit?
There's no upload limit because nothing is uploaded. Your device's memory sets the practical limit, so very large batches of big photos may be slow on a phone. Convert in smaller batches if your browser struggles. Closing other tabs gives the tool more memory to work with.
