The Image Format Converter changes images between PNG, JPG, and WEBP right in your browser. Drop in one or many files, pick a target format, and download the converted images — no upload, no waiting, and nothing leaves your device.
Different formats suit different jobs: PNG for graphics and transparency, JPG for photos, and WEBP for the smallest files on the web. Converting between them is a constant need when preparing images for a site, an app, or a document, and this tool does it in a click, showing you the file-size change for each image.
How to convert image formats
- Drop your images onto the box or click to upload (you can add several at once).
- Choose the target format — PNG, JPG, or WEBP.
- For JPG and WEBP, adjust the quality slider to balance size and detail.
- Download each converted image, or use “Download all”.
Which format should you use?
PNG is lossless and supports transparency, making it ideal for logos, icons, screenshots, and any graphic with sharp edges or a transparent background. JPG is lossy and has no transparency, but compresses photographs well, so it suits photos and complex images where small artefacts are acceptable. WEBP is a modern format that usually beats both — smaller than JPG at similar quality and it supports transparency like PNG — which is why it is the default choice for fast-loading websites. Converting a PNG or JPG to WEBP is one of the easiest ways to cut image weight.
Quality and transparency
PNG conversion is lossless, so there is no quality setting. JPG and WEBP are compressed, so a quality slider lets you trade file size against fidelity — around 80–90% is usually indistinguishable from the original while saving a lot of space. One thing to know: JPG cannot store transparency, so when you convert a transparent PNG to JPG, the transparent areas are filled with white. Convert to WEBP or keep PNG if you need to preserve transparency.
Private, batch, and browser-based
Every conversion runs locally using the browser’s canvas, so your images are never uploaded to a server — good for screenshots, documents, and anything sensitive. You can convert many files in one go and download them individually or all at once. Note that converting to PNG or JPG flattens animation, so an animated GIF becomes a single still frame; use it for static images.
Frequently Asked Questions
How do I convert PNG to JPG (or JPG to PNG)?
Upload the image, choose the target format, and download the result. PNG to JPG will fill any transparent areas with white, since JPG has no transparency.
How do I convert an image to WEBP?
Upload it, select WEBP, and adjust the quality if you like. WEBP is usually much smaller than PNG or JPG at the same visual quality, which is great for websites.
Will converting reduce the file size?
Often, yes — especially converting to WEBP, or JPG/WEBP at a lower quality. The tool shows the before-and-after size and the percentage change for each image.
Does it keep transparency?
PNG and WEBP keep transparency; JPG does not, so transparent pixels become white when you convert to JPG. Choose PNG or WEBP to preserve a transparent background.
Are my images uploaded anywhere?
No. Conversion happens entirely in your browser using a canvas, so your images never leave your device.
Can it convert animated GIFs?
It converts the image to a single still frame — PNG, JPG, and WEBP output here are not animated. Use it for static images.
