Convert an image
Nothing is uploaded — processing happens in this tab
PNG, JPG, WebP, GIF or BMP in, up to 12 MB and 4000 x 4000
Three steps, about a minute
Choose your image
Drop a PNG, JPG, WebP, GIF or BMP into the tool above or pick it from your device. Nothing leaves this tab.
Pick the output format
PNG for transparency and sharp edges, JPG for photographs going somewhere you do not control, WebP for your own website, BMP only if something old asks for it.
Set the quality and download
The slider matters for JPG and WebP. Check the size and the saving printed under the preview, then save the file.
The conversion, and the reason for it
- Four output formats. PNG, JPG, WebP and BMP, so you can match whatever the destination names rather than arguing with it.
- The saving is printed. New resolution, new file size and the percentage difference, so you can tell whether the conversion was worth making.
- Quality is yours to set. One slider from 10 to 100, which changes JPG and WebP and is correctly ignored for the lossless formats.
- Nothing is uploaded. The conversion runs in this tab on your own device, which is faster than a round trip and settles the privacy question before it is asked.
About this tool
Which format should I convert to?
It depends on where the picture is going, not on which format is smallest. JPG for photographs headed to an upload form or somebody else’s inbox, PNG for screenshots, logos and anything transparent, WebP for a website you control. There is a full guide with a three-question picker if you want to be sure.
Will converting to JPG remove my transparent background?
Yes. JPG has no alpha channel, so transparency becomes a solid colour — usually white. If the background needs to stay see-through, convert to PNG or WebP instead.
Does converting lose quality?
Converting to PNG or BMP is lossless, so nothing is discarded. Converting to JPG or WebP is lossy and discards some detail, which is what the quality slider controls. Convert once from the original rather than re-saving a file that has already been compressed.
Can it convert HEIC photos from my iPhone?
Not currently — the input formats are PNG, JPG, WebP, GIF and BMP. On iOS you can set the camera to Most Compatible so photos are saved as JPG, or share the photo to yourself, which usually converts it on the way.
What about animated GIFs?
An animated GIF can go in, but only the first frame comes out, because PNG, JPG and BMP have no concept of animation. Converting an animation is a different job from converting an image.
