About this tool
Photos from a modern phone are often five to ten megabytes each, which is too large for an email attachment, a job application form, or a website upload. This makes them smaller, and lets you set a maximum width so a 4000-pixel photo becomes a sensible size for the screen it will actually be viewed on.
The difference from most tools that do this: your photo is never uploaded. It is read and resized by your own browser, so a passport scan or a picture of your children is not sitting on a stranger's server waiting to be deleted. Turn off your internet after the page loads and it still works.
How to compress a photo without uploading it
- Add your photos. Drag them onto the box, or click to choose files. You can do several at once.
- Choose how small. Pick a quality level and, if you like, a maximum width. Smaller quality means a smaller file.
- Check the result. Each photo shows its original size, its new size, and how much was saved. Compare before you commit.
- Download. Save each photo, or download them all. The originals on your device are never changed.
What it supports
- JPEG, PNG, WebP and most common photo formats
- Several photos at once
- A maximum width, so large photos are scaled down as well as compressed
- Output as JPEG or WebP — WebP is usually 25 to 35 per cent smaller
- Photos of any size your device can open, including very large ones
Questions
Is my photo uploaded anywhere?
No. This is the main reason the tool exists. Your browser reads the file from your device, resizes it in memory and hands it back to you. Nothing is transmitted, stored or logged, and there is no server involved at all. Disconnect from the internet after the page has loaded and it will still work.
How much smaller will my photo get?
It depends on the photo, but a typical phone picture at the default settings drops by 70 to 90 per cent — often from about 5 MB to under 500 KB — with no visible difference on a screen. The tool shows you the exact saving for each file before you download.
Will it make my photo look bad?
At the default quality, almost never for on-screen use. Lower quality settings trade detail for size, and you can see the result before downloading. If a photo is going to be printed large, use a higher quality or keep the original.
What is the difference between quality and maximum width?
Quality controls how much detail is thrown away within the image. Maximum width shrinks the number of pixels. For most uses, reducing the width is what saves the most space — a 4000-pixel-wide photo is far larger than a screen needs.
Should I choose JPEG or WebP?
WebP files are usually 25 to 35 per cent smaller than JPEG at the same visible quality and work in every current browser. Choose JPEG if the file has to open in older software, or if you are sending it to someone who might use an older system.
Are my original photos changed?
No. The tool only reads them. Your originals stay exactly as they are, and you get new compressed copies to save wherever you like.
