How to use
1. Choose a photo. 2. Set your target and format. 3. Compress, inspect the result and download.
Will every image keep its original quality?
Lossy compression can remove detail. Smaller targets may also require smaller dimensions. Always inspect the downloaded image.
Are my images uploaded?
This tool uses your browser to decode and compress your selected image. It does not send the image to a processing server.
Is there a Pro version?
Not yet. This tool offers single-image compression for free. Paid features and checkout are not enabled.
Guide: reduce a photo to 20, 50, 100 or 200 KB
When an application form rejects a photo because its file is too large, check two requirements separately: maximum file size and required pixel dimensions. A 100 KB limit describes the amount of data in the file; a 600 × 600 requirement describes its width and height. Meeting one does not automatically meet the other. Read the receiving website’s instructions before changing a passport photo, identity document or other important image.
Choose a suitable target
Select your original JPG, PNG or WebP and enter the maximum size in KB. This tool treats one KB as 1,024 bytes. If a form uses a different measurement or rejects a file near its limit, choose a slightly lower target. Start at 200 KB for ordinary uploads, or use 100, 50 or 20 KB when the form specifically requires it. A smaller target usually removes more detail. Keep a copy of the original.
Pick the output format
JPG is a practical choice for photographs and many online forms. It cannot preserve transparency, so transparent areas become white. WebP may produce a smaller photo, but some upload forms do not accept it. Check the accepted formats before downloading. A PNG input can be converted to JPG or WebP here; PNG output is not offered by this compressor. Use the Image Format Converter when a different output format matters more than a target size.
Decide whether resizing is allowed
With “Allow resizing” enabled, the tool first adjusts compression quality and can then reduce dimensions to meet the target. Disable this option if you must keep the original pixel dimensions. The target may then be unreachable. The result reports both its actual size and dimensions, so check them before submitting the file. To set a specific width and height, use the Image Resizer first.
Review before uploading
Inspect faces, small text, fine edges and colours in the preview. Download the result and open it on your device. If text becomes hard to read or a face looks blurred, use a higher target or return to your original. Compression is not a repair tool and cannot restore detail missing from the source. Avoid repeated compression of an already compressed file.
Frequently asked questions
Is it free, and do I need an account?
Single-image compression is free and needs no signup. There is currently no paid checkout or Pro subscription.
What are the file limits?
Choose one JPG, PNG or WebP up to 20 MB and 40 megapixels. Targets range from 10 to 20,000 KB. A very large photo can still exceed the memory available on a phone.
Will every image reach exactly my target?
No. The tool aims for a file at or below the target, rather than padding it to an exact size. Some combinations of size, dimensions and format cannot be met. The displayed result tells you whether the target was reached.
Does this work on mobile?
It is designed for modern mobile and desktop browsers. Keep the tab open during processing. Try a smaller source image if your browser runs out of memory.
Does compression remove private metadata?
Do not rely on this tool as a privacy or metadata removal service. Check the downloaded file with a suitable inspection tool before sharing sensitive images.
