Image Compressor
Make photos and screenshots lighter for websites, email and messaging. Pick a quality level, optionally cap the width, and compare the original and compressed sizes before downloading.

Upload forms often ask for 20, 50, 100 or 200 KB. PNG files are saved as JPG in this mode.

How to use
- Add one or more images (JPG, PNG, WebP, GIF or BMP).
- Choose an output format and quality. 70–80% is a good balance for photos.
- Or switch the goal to “Target file size” and enter the limit an upload form asks for, such as 50 KB or 100 KB.
- Optionally set a maximum width so very large photos are scaled down too.
- Press Compress, use Compare to check the quality, then download each file or all of them as a ZIP.
Examples
A job or exam portal that only accepts photos under 50 KB
Choose “Target file size”, press 50 KB and use JPG. The tool finds the highest quality that fits and only reduces the dimensions if quality alone is not enough.
A 4 MB phone photo for a blog
WebP, quality 75, max width 1600 px usually gives a file of a few hundred kilobytes with no visible loss on screen.
A PNG screenshot with text
Keep PNG for sharp text, or try WebP at 90% — screenshots with flat colours compress very well.

Frequently asked questions
How does the target file size work?
For each image the tool tries several quality levels and keeps the highest one that stays under your limit. If even low quality is too big, it scales the image down step by step. Files that still cannot reach the limit are marked so you can choose a larger target. PNG has no quality setting, so target mode saves PNG files as JPG (or WebP if you chose it).
Why did my PNG get bigger?
PNG is lossless, so the quality slider has no effect on PNG output. Re-encoding an already optimised PNG can produce a slightly larger file. Convert to WebP or JPG for real savings; the tool always shows you the result so you can keep the original if it is smaller.
Is metadata kept?
No. Re-encoding through the canvas drops EXIF data such as camera model and GPS location, which is usually what you want before publishing.
Is there a size limit?
Files up to 50 MB each are accepted. Very large images use a lot of memory, so phones may struggle above roughly 40 megapixels.
