About
What Resize Image does
Resize an image to an exact width and height in pixels, or by a percentage. The proportions stay locked unless you unlock them, so nothing is stretched by accident, and the size the file will come out at is shown before you download it.
Drop a photo and the image editor opens right here on its Resize tab. Crop, straighten or adjust it in the same place if it needs it — the resize is applied last, from the original, at full quality.
Everything happens on your own machine: the file is decoded, processed and re-encoded by your browser, and never leaves your device. There is no upload, no queue and no account.
Why this one
Why use Resize Image here
-
Exact, or by eye
Type a width and height in pixels, pick a percentage, or drag the handles. The size it downloads at is shown as you go.
-
Nothing stretched by accident
The proportions stay locked until you unlock them, so a portrait photo never comes out squashed.
-
Resized once, from the original
At download, your edits and the resize run again from the original file, so nothing is scaled twice.
-
Undo, and more than resizing
Undo any step, and crop, straighten or adjust light and colour in the same place if the photo needs it.
How it works
How to use Resize Image
-
Drop in an image, click to browse, or paste one. It opens in the editor on the Resize tab; you can add more and switch between them.
-
Type a width or a height in pixels (the other side follows while the lock is on), switch to Percentage, or drag the handles around the picture.
-
Check the size shown under the fields: it is exactly what the download will be.
-
Download from the top bar, or from Export to choose the format and quality.
Questions
Frequently asked
How do I resize an image?
Drop it here and it opens on the Resize tab. Type the width or height you want in pixels, pick a percentage or drag the handles, then download. The proportions stay locked unless you unlock them.
Will resizing distort my image?
Not unless you ask it to. With the lock on, changing one side changes the other in proportion. Unlock it to set both sides yourself; if you want a different shape without squashing anything, crop to that shape first, then resize.
Can I make an image bigger?
Yes, up to four times the size or 16,384 pixels a side. But no tool can add detail a camera never captured: enlarging fills in between the pixels that exist, so a big enlargement looks softer than a true high-resolution original. The tool says so when you go above the original size.
Does resizing lose quality?
Shrinking an image throws away pixels by definition, but nothing else is lost along the way: the resize is rendered once, from your original file, at the size you asked for. Nothing is scaled from a preview or resized twice. A PNG stays a PNG unless you choose otherwise in Export.
Is my image uploaded to resize it?
No. It is resized in this page, on your device. There is no upload and no copy of your image anywhere else.
Does resizing make the file smaller?
Making an image smaller in pixels shrinks the file a great deal, often far more than compression alone. For the smallest file, resize first, then run it through Compress Image.
What size should I use for email or a website?
For email and most web pages, 1,200 to 2,000 pixels across is plenty. Phone photos are often 4,000 pixels or more, which is why they are slow to send.
Can I resize several images at once?
Not in one go yet: each image keeps its own size. Add several and switch between them to size each one.
