Open toolThese free image tools solve the everyday problems that come with photographs: a file too big for an upload form, an image with the wrong dimensions, or a picture in a format something will not accept.
All of them work on your own device. Photos are personal - holiday pictures, scanned documents, screenshots of private conversations - and none of these jobs need a server, so none of them use one.
Which image tool do you need?
- To get a photo under a size limit, use the free image compressor. It can search for the quality that lands nearest a target you specify in KB.
- To change the pixel dimensions, use the free image resizer. The aspect ratio is locked by default so nothing gets stretched.
- To turn a JPG into a lossless PNG, use the free JPG to PNG converter.
- To turn a PNG into a much smaller JPG, use the free PNG to JPG converter - it flattens transparency onto white rather than black.
Resize first, then compress
These two get confused constantly, and the order matters. Resizing reduces the number of pixels. Compressing keeps the pixels but stores them less precisely.
A photo straight off a phone might be 4000 pixels wide and four megabytes. Displayed in an 800-pixel column, it carries five times more detail than anyone will ever see. Resizing to 1600 pixels and then compressing at around 80% quality routinely takes that four-megabyte file under 200 KB with no visible difference. Compressing alone would never get close.
Choosing a format
- JPG for photographs. Much smaller than PNG, and the compression is hard to see on photographic content.
- PNG for screenshots, diagrams, logos and anything needing transparency. Lossless, so text and line edges stay sharp.
- WebP when you want both - it compresses better than JPG and still supports transparency. Every current browser handles it.
- Never PNG for a large photograph destined for the web. The file will be several times bigger with nothing gained.
Frequently asked questions
Are these image tools free?
Yes - all of them, with no sign-up, no watermark and no limit on how many images you process.
Are my images uploaded anywhere?
No. Your images never leave your device. They are decoded and re-encoded by your browser, so nothing is transmitted and no copy is stored.
How do I compress an image to a specific size, like 200 KB?
Open the free image compressor, turn on "Aim for a specific file size" and enter your target. It searches for the highest quality that still fits.
What happens to transparency when I convert a PNG to JPG?
It is flattened onto white. JPG cannot store transparency at all, and white is far more useful than the black that converters produce when they simply drop the alpha channel.
Is there a file size limit?
No fixed limit, because nothing is uploaded. The practical ceiling is your device's memory - a very large image may be slow on an older phone.
Will resizing distort my image?
Not with the aspect ratio locked, which is the default. Changing one dimension updates the other automatically.
