Image Tools
Resize, compress, convert images.
Free to use · No sign-up needed
Choose an image, or drag one onto this box. It stays on your device.
Size
Nothing is uploaded. Your image is opened, redrawn and saved by this page, on your own device, and files up to 25 MB are welcome.
Make an image smaller without sending it to a stranger
Nearly every image tool on the internet asks you to upload the picture first. For a holiday photo that is merely rude. For a screenshot of a contract, a passport scan or a whiteboard after a planning meeting, it is a decision you have made on someone else's behalf.
This one does not ask. Pick an image, set a width, choose a format, press the button. The picture is opened, redrawn and saved by this page on your own device, which is why there is no sign-up, no watermark and no link to share: there is nothing anywhere to share.
How to use it
- Choose an image, or drag one onto the box.
- Set a width. The height follows on its own unless you untick the box.
- Pick a format: PNG, JPEG or WebP.
- For JPEG and WebP, move the quality slider. Lower means smaller.
- Press Make the image. The new size appears, so you can judge it.
- Press Download image, or change something and make another.
Picking a width that fits
Most images are far bigger than the thing they are going into. A phone photo is around 4000 pixels wide; a picture in a document or a slide is rarely more than 1600. Resizing to the width you actually need takes more weight off a file than any amount of fiddling with quality, because you are throwing away pixels nobody was going to see.
Then compress. At 80% quality a JPEG is a fraction of the size and the difference is invisible; below about 50% the edges go mushy and flat areas grow blotches. Make the image, read the new size, try another number. Two presses tell you more than any rule of thumb.
Good uses
- A photo too big to attach to an email, which is why most people end up here.
- Screenshots for a document, where a 6 MB PNG becomes a 200 KB JPEG nobody can tell apart.
- A PNG for somewhere that only takes JPEGs, or either for somewhere that wants WebP.
- Anything private enough that uploading it to a free website would be a bad idea.
Nothing you pick leaves this page
Browsers have been able to decode, draw and re-encode an image for years, so a tool doing this has no honest reason to want your file. There is no upload step here to quietly keep a copy from, and no account to attach anything to. The image never becomes a request: it goes from your disk into this tab's memory and back out as a download.
A useful side effect comes free with that. The picture is redrawn rather than edited, so the new file carries no camera, no date and no GPS coordinates from wherever it was taken.
What it will not do
There is no cropping, no rotating and no filters: this is three jobs, and doing only those three in one screen is the point. It also cannot make a small image genuinely bigger — stretching 400 pixels to 2000 gives you a blurry 2000, because the detail was never recorded. Start from the original where you can, rather than from something already squeezed.
Questions people ask
- Is my image uploaded anywhere?
- No, and there is nowhere for it to go. The page opens the file, redraws it and saves it again using your browser's own machinery, on your own device. Turn the network off after the page loads and the tool still works, which is the clearest proof there is.
- Which format should I pick?
- JPEG for photographs, because it is small and nobody can see the difference at 80%. PNG for screenshots, logos, diagrams and anything with flat colour or a transparent background. WebP when the place you are sending it accepts WebP, because it is usually the smallest of the three at the same quality.
- What happens to a transparent background if I save as JPEG?
- It turns white. JPEG has no transparency at all, so something has to go behind the picture, and white is the least surprising answer. The tool says so on screen before you press the button rather than after, and picking PNG or WebP instead keeps the transparency.
- Does this remove the information stored inside the photo?
- Yes, as a side effect. The image is redrawn pixel by pixel and saved fresh, so the camera model, the date and any GPS coordinates the original carried do not make it into the new file. The one piece of metadata that is honoured first is the rotation tag, which is baked into the pixels so the picture comes out the right way up.
- Why does it refuse enormous files?
- Because the work happens in a browser tab rather than on a server, and a tab has a limited amount of memory. A decoded image needs several times the room its file takes, so the tool stops at 25 MB and 40 megapixels — past either of those, a phone would simply reload the page mid-job and give you nothing.
