Resize an image
To the exact size you need, or a ready one with its source. Many photos at once, and your browser does the work, so nothing is uploaded and there is no daily limit.
Drop photos here
or paste one (Ctrl+V or ⌘V)
or take a new one with the camera
In: JPG, PNG, WebP, AVIF, GIF (its first frame) or BMP; HEIC in Safari, and in Chrome or Edge where the device plays HEVC video. As many as you like.
Your photos
How it works
- Choose a ready size, or type a width, a height or both, in pixels, percent, centimetres, millimetres or inches.
- If you typed both sides, choose what happens when the shape changes: keep the shape, crop, add borders or stretch.
- Choose, drop or paste one photo or many; each is resized at once, with its size before and after.
- Download each file, or all of them as one ZIP. Change a setting and every photo is made again.
Why this one
- Nothing is uploaded
- Many resizers send your photos to their servers and keep them for hours. Here your own browser does the work, so they never leave your device.
- Sizes with their source
- A ready size names the platform's own help page and the day we read it, so you can check it. Where a platform's page could not be read, we offer no number rather than repeat someone else's.
- You see what a new shape does
- Each of the four choices says in a sentence what it does, and a large preview shows your first photo as it will be saved. Borders can be any colour or transparent.
- Sizes for print
- Centimetres, millimetres and inches at the DPI you set, and a JPG or PNG carries that DPI in the file, so A4 prints as A4.
- Upright and private
- A phone photo is turned the way it was taken, and the new file carries none of the photo's hidden details: not the camera, not the date, not the place.
Questions
How do I resize an image without losing quality?
Making a photo smaller keeps it sharp. Making it larger cannot add detail that was never there, so it can look soft; this page says when that happens, and you can turn enlarging off. For the best result, start from your largest original and save as PNG, or as JPG at quality 85 or more.
What is the difference between resizing and compressing?
Resizing changes the number of pixels, so the picture has new dimensions. Compressing keeps the dimensions and makes the file smaller. A smaller picture usually makes a smaller file too; if a form asks for a limit in KB, use the Compress to KB tool, which aims for that number.
What size in pixels is A4?
At 300 DPI, A4 (210 × 297 mm) is 2480 × 3508 pixels; at 150 DPI, half that on each side. Choose A4 in the list, or type millimetres and a DPI, and this page works it out.
What does DPI change?
DPI says how many pixels are printed in each inch; it does not change the picture on a screen. At 300 DPI a 1200 × 1800 pixel photo prints at 4 × 6 inches. When you resize in centimetres, millimetres or inches, the DPI decides how many pixels the file has.
How can I make a photo square without cutting anything off?
Type the same number for width and height, and choose Add borders: the whole photo sits in the middle, with the colour you choose, or transparent, on the two sides left over.
Can I resize many photos at once?
Yes, as many as you like: there is no limit and nothing to pay. Every photo gets the same settings; with Keep the shape, the two numbers act as maximums, so tall and wide photos each keep their own shape. Download them one by one or as a ZIP.
Why does the ready YouTube size look so large?
It is the size YouTube's own help page gives for a video's thumbnail, 3840 × 2160 pixels. That page also allows a smaller one, as long as it is at least 640 pixels wide and 16:9, so you can type a smaller size with the same shape.
Are my photos uploaded?
No. Your browser opens, resizes and saves each photo on your device. The page makes no request with your photo in it.
