Image Compressor
Reduce a photo to a target size (20–3,000 KB, e.g. 200 KB) or a max width, in bulk, and save as JPEG, WebP or PNG.
How to use
- Choose photos or drop them in. Several files at once and pasting with Ctrl+V both work.
- Pick a mode. Target size tunes the quality automatically to fit a KB limit (20–3,000 KB); Pixel width only shrinks the width and saves at 90% quality.
- Set the max width in px and the output format (JPEG, WebP or PNG). Photos wider than the limit are scaled down; smaller ones are never enlarged.
- After changing a setting, press Compress to run again. Each photo shows its original size, new size, percentage saved and dimensions.
- Press Download, or Download all for every file. File names end in -compressed-WIDTHxHEIGHT.
FAQ
How do I get a photo under 200 KB?
Choose Target size, set the slider to 200 KB and save as JPEG or WebP. The tool searches for the highest quality that stays under the target. If the result is still larger, a note appears on its card; lower the max width and compress again.
Which files can I load?
Any image your browser can open, such as JPG, PNG, WebP or GIF. An animated GIF uses its first frame, and formats the browser cannot decode (HEIC in some browsers) are skipped with a message.
Will the quality drop a lot?
JPEG and WebP are lossy, so the smaller the target the lower the quality. For a large photo, lowering the max width first usually looks cleaner at the same file size. The original is never changed; the result is saved as a new file.
Does it shrink PNG files too?
PNG is lossless, so the quality tuning for a target size has no effect on it. To cut the size a lot, save as JPEG or WebP or reduce the max width. A transparent PNG saved as JPEG gets a white background.
What is the Pixel width mode?
It only scales the width down and saves at 90% quality, with no target size. A photo that is already small and heavily compressed can come out larger in this mode.
Can I compress several photos at once?
Yes. Add several files and they are compressed one after another with the same settings. Download each one, or use Download all; the files are not zipped, and your browser may ask permission for multiple downloads.
What happens to resolution and photo metadata?
Photos wider than the max width (1,920 px by default) are scaled to that width; smaller ones keep their size. Each card shows the resulting width × height. The saved file is redrawn, so EXIF data such as the shooting location is not carried over.
Are my settings remembered?
The mode, target size, max width and output format are stored in this browser and come back next time. Photos are not part of the settings, so you add them again after reopening the page.
