Scale images to an exact size, in bulk.
Processed on your device — never uploaded

About this tool
Scale a photo to the exact width a form demands, or push a whole folder of product shots through the same size in one go. Lock the aspect ratio or set both edges, choose how the image fits, and take away a single file or a ZIP of the lot. There is no file-count limit, because there is no server charging us per upload.
Your files never leave your device. Toolpit has no upload step and no server that can see your document — the work happens in this tab, on your machine, and stops the moment you close it.
How to resize an image
Drop in one image or a whole folder of them.
Set a width, a height, an exact box or a percentage.
Resize and download the images, or take them all as a ZIP.
Questions
Are my images uploaded?
No. There is no upload step and no server that could receive the file — the tool runs as code in this browser tab, works on the copy your browser opened, and forgets it when you close the tab. You can check this yourself: open your browser’s network panel and run the tool. You will see the page, its scripts and the ads that pay for the site — and no request carrying your file, because there is no endpoint to carry it to.
How many images can I resize at once?
There is no limit. Batch tools elsewhere cap you at ten or twenty files because each one costs them an upload and a server round trip; here the work happens on your machine, so the only limit is its memory.
Will resizing make my image blurry?
Shrinking is done in halving steps rather than one jump, which averages the pixels properly and avoids the crunchy, aliased look you get from a naive resize. Enlarging is a different matter — there is no new detail to add, which is why "never enlarge" is on by default.
What is the difference between fit, fill and stretch?
Fit keeps the whole image and pads the leftover space. Fill covers the box completely and trims the overflow. Stretch forces both edges and distorts the picture — it is there because occasionally you genuinely need it, not because you should.
