Resize an image
Change the size of your images right in your browser, free and with no limits. Type the exact width and height in pixels —with the aspect ratio locked so they don’t get distorted—, scale down by a percentage or use the most common preset sizes (Full HD 1920×1080, 4K, square 1080×1080 for Instagram, 1080×1920 for stories…). You can resize many images at once with the same settings and download them all in a ZIP. Unlike most resizing sites, which upload your photos to their server, make you create an account or charge to process batches, nothing is uploaded here: everything happens on your device, with no sign-up, no watermark and no limit on the size or number of images. On top of that, the resizing uses high-quality resampling (step-by-step downscaling) to keep the picture sharp and strips out the EXIF metadata along the way.
How to resize an image
- Drag in your images or click to choose them (add as many as you like).
- Choose how to change the size: by dimensions in pixels or by percentage.
- Type the width and height (or pick a preset size) and leave “Keep aspect ratio” checked.
- Choose the output format (PNG, JPEG or WebP) and, if it applies, the quality.
- Click “Resize” and download each image or all of them together in a ZIP.
Frequently asked questions
Are my images uploaded to a server?
No. All the resizing happens in your browser with the Canvas API; your images never leave your device and the tool keeps working offline once loaded. It is a real difference: most resizing sites upload your photo to their server to process it and hold on to it for a while.
How do I change the image to exact pixel dimensions?
In “Dimensions” mode, type the width and height you want in pixels. With “Keep aspect ratio” on, the image fits inside that width and height without stretching; if you leave one field empty, the other is worked out for you. You can also pick a preset size (Full HD, 4K, Instagram square, story…).
Does the image get distorted when I resize it?
No, as long as you keep “Keep aspect ratio” on: the image is scaled proportionally to fit the sizes you enter. If you untick that option, it is stretched to exactly the width and height you type (which can distort it), something that is only useful when you truly need one exact size.
Can I scale down by percentage?
Yes. Switch to “Percentage” and choose what percentage of the original to scale down to (for example, 50% for half the width and height). It is the quickest way to lighten a batch of photos while keeping the aspect ratio.
Do I lose quality when resizing?
Downscaling keeps quality very high: we use high-quality resampling that reduces the size in steps (halving each time) to avoid jagged edges and keep the image sharp. Enlarging a small image, on the other hand, always makes it blurry; that is why the “Don’t enlarge (downscale only)” option is on by default, though you can untick it if you really do need to make it bigger.
Can I resize many images at once?
Yes. Drag in a whole batch, apply the same settings to all of them at once and download them one by one or all together in a ZIP. There is no limit on the number of images or on their size, because everything runs on your own device.
Which formats does it support and what does it save to?
It opens JPG, PNG, WebP, GIF and any other format your browser can display. The output can keep the original format or be converted to PNG (which preserves transparency), JPEG or WebP; the quality control applies to JPEG and WebP.
How is this different from cropping or compressing an image?
Resizing changes the size of the whole image without removing anything. Cropping keeps one part and discards the rest (it changes the framing). Compressing aims to shrink the file size with professional codecs. For the first, use this tool; for the others, “Crop image” and “Compress image”.
Is it free? Does it have limits, an account or a watermark?
It is completely free, with no sign-up and no limit on uses or size, and we don’t add any watermark. It is the exact opposite of many sites: some force you to create an account, others stamp their mark on the result of the free plan, cap the batch size or only offer resizing through a paid API. None of that here, and nothing is uploaded.
