Image Compressor
Drop in one or more images and this image compressor shrinks the file size while keeping the format you started with. Nothing is uploaded: your browser does the work and the result downloads straight to your device.

How much can an image be compressed?
It depends on the image. A busy photo with a lot of detail, such as a landscape or a crowd, can usually drop 60 to 80 percent at a quality setting of 80 with no change you would notice at normal zoom. Flat graphics and screenshots compress even further because there is less detail for the compressor to preserve.
Quality mode or target size mode, which should you use?
Quality mode is the better starting point when you just want a smaller file and are not chasing an exact number: drag the slider, watch the before and after size, stop when it looks right. Target size mode is for when something else sets the rule, such as a government form capped at 100 KB or an upload form that rejects anything over 1 MB. Type the number in kilobytes and the tool searches for the highest quality that still lands under it, so you are not guessing at slider positions.
Why compress an image before uploading it anywhere?
Most upload forms, job portals and content management systems have a size limit, and a phone camera or screenshot tool routinely produces files well past it. Compressing first avoids the upload failing outright, and it also means the page or form that eventually displays the image loads faster for whoever views it next, since a smaller file downloads sooner on a slow connection.
Frequently asked questions
Does compressing an image reduce its quality?
A little, depending on the setting. At quality 80 or above, most photos show no visible difference. Push the slider lower and you trade more file size for more visible softness, which is useful for thumbnails and forms with a strict size limit.
Will this change my image dimensions?
No, unless you turn on the optional resize setting. By default only the file size changes, not the width or height.
Is there a limit on how many images I can compress?
You can drop in up to 50 images per batch, each up to 50 MB. There is no daily limit and no account needed.
Which file formats does this accept?
JPG, PNG, WebP, GIF and BMP. The output keeps whatever format you started with unless you turn on the convert option and pick a different one.
Why is my PNG not shrinking as much as my JPG?
PNG uses lossless compression, so the quality slider works differently: it reduces the colour palette rather than blurring detail. A photo saved as PNG will almost always compress further if you convert it to JPG first, since JPG's lossy compression is built for photographic detail.
Does the tool remove my photo's location data?
Yes. EXIF metadata, including GPS coordinates and camera information, is stripped from every output automatically, whether or not you change the quality.
