Image Compressor
Open Image Compressor and add an image.
Choose a mode at the top: Quality or Target size.
In Quality mode, pick the Output format (Same as input, JPG, WEBP or PNG) and move the Quality slider (10–100%, default 75%).
For PNG output, the slider is Colors instead (16 to 256, default 256). Fewer colours give a smaller file; 256 looks the same as the original for most images.
In Target size mode, type a Target size (KB) or select one of the shortcuts for 100 KB, 500 KB or 1 MB. The result is always a JPG, and transparent areas become white.
Select Compress image, check the result, and select Download.
The download is named after the original with -compressed added. If the target size cannot be reached without ruining the image, the page says so and gives you the smallest safe result.
Reduce Image Size
This is the quickest way to meet an upload limit on a form or portal.
Open Reduce Image Size and add an image.
Under Target size, select 100 KB, 500 KB or 1 MB, or Custom and type a size in KB (10 to 20480).
Select the button, which names the target, for example Reduce to 500 KB.
Select Download.
The result is a JPG named after the original with the target added, for example photo-500kb.jpg. The page also shows the new size and pixel dimensions. If the image is already under the target, the page tells you, and you may not need to change it at all.
Image Resizer
Open Image Resizer and add an image.
Choose Exact pixels or Percentage.
- Exact pixels: type Width (px) or Height (px). The lock button between them keeps the proportions; select it to unlock and set both freely.
- Percentage: drag the Scale slider (1–200%, default 50%). The new size is shown next to it.
Pick an Output format: Same as input, JPG, PNG or WEBP. For JPG and WEBP, set Quality (default 90%).
Select Resize image, then Download.
The download name includes the new size, for example photo-1280x960.jpg. The largest output is 12000 pixels on a side. If you enlarge an image beyond its original size, the page warns that it may look soft or blurry.
Format converters
JPG to PNG, PNG to JPG, JPG to WEBP and WEBP to JPG work the same way and take up to 30 files at once.
Open the converter you need.
Drop the images on the box, or click it to choose them. Only the matching input format is accepted, for example PNG files on PNG to JPG.
For JPG and WEBP output, set Quality (default 90%).
When converting to JPG, choose a Background for transparency. Transparent areas are filled with this colour (white by default), because JPG cannot store transparency.
Select the convert button, for example Convert 5 files to JPG.
Select Download next to each finished file.
Each row shows the size before and after, and the change in percent. Results keep the original name with the new extension. The bin button removes a file from the list.
Good to know
PNG is lossless, so JPG to PNG usually makes files bigger, not smaller. Use it when you need a format that keeps every pixel, not to save space.
WEBP Converter
WEBP Converter turns one JPG or PNG into WEBP and shows the result next to the original.
Open WEBP Converter and add a JPG or PNG.
Set Quality (default 80%). Raise it to 90% or more for screenshots and images with sharp text.
Select Convert to WEBP, then Download WEBP.
WEBP keeps transparency, so transparent areas of a PNG stay transparent.
