resize images
Give one image or a hundred a new size, in this tab. The proportions are kept, and nothing is sent anywhere.
There is no Google Drive or Dropbox button on purpose: those send the file through a server. Here is what happens instead.
in three steps
- Drop your images in, or choose them. Their real dimensions appear beside each name.
- Say what the number means — longest side, width, height or a percentage — and give it a value.
- Resize, and take the files. Each new width goes into its filename, so nothing overwrites the original.
how it works
Choose what the number means — longest side, width, height or a percentage — and every image in the batch is fitted to it. Proportions are always kept, so a portrait and a landscape photo given the same longest side both end up inside the same square.
Each file is decoded, drawn at the new size and written back in its own format. The new width goes into the filename, so holiday.jpg resized to 1600 comes back as holiday-1600.jpg and does not overwrite the original in your downloads folder.
why doing this locally matters here
Resizing is the step people reach for when a file is too big to attach or upload — which means the images being resized are often the ones that were too sensitive or too large to hand over in the first place: a scan of a passport for a form, a photograph of a contract, a screenshot of an account page.
Sending those to a resizing service to make them smaller is a strange trade. Here the work is done by the browser you already trust with the file, so the only copy that exists is the one you save.
questions
Where does my image go?
Nowhere. Your browser decodes the file, draws it at the new size onto a canvas and writes the result back out, all inside this tab. No request carries the image, and the job log under the tool counts the requests the page made while working and how many left this site — the second number is zero, and your browser's network panel will say the same.
Will resizing stretch my image?
No. The tool always keeps the original proportions: you choose one dimension and the other follows. That is why there is no separate width and height pair to fill in — a pair lets you enter a ratio that does not match the image, and the result is a squashed picture.
What does "longest side" mean?
It fits the image inside a square of that size whichever way round it is. A landscape photo gets that width; a portrait photo gets that height. It is the setting you want when a batch contains both orientations and you need them all to fit the same space.
Can I make a small image bigger?
You can switch on "enlarge images that are already smaller", but it cannot add detail that the camera never captured — the result will look soft. Enlarging is off by default so a batch of mixed sizes does not quietly blow up the small ones.
Does resizing lose quality?
Making an image smaller throws away pixels by definition, which is the point. The tool writes the result at a high quality setting so the reduction itself is not compounded by heavy compression. If you want a smaller file rather than smaller dimensions, compress it instead.
Is this really free?
Yes, with no account and no paid tier. Advertising pays for the hosting. Since your images never reach us, there is nothing about them to sell and nothing for us to store.
