How to resize an image
- Drop your image onto the box above, or click to browse for one.
- Type the width or height you want. With "keep aspect ratio" ticked, the other side follows automatically.
- Or use a quick scale button to halve, quarter or double the image.
- Download the result.
Common sizes worth knowing
- Instagram post — 1080 × 1080 (square) or 1080 × 1350 (portrait)
- Instagram story / Reel — 1080 × 1920
- YouTube thumbnail — 1280 × 720
- Facebook cover — 851 × 315
- LinkedIn banner — 1584 × 396
- Full HD wallpaper — 1920 × 1080
- Passport-style photo — 600 × 600 at 300 DPI (check your local requirement)
Should I keep the aspect ratio?
Almost always, yes. Aspect ratio is the relationship between width and height. If you change one without the other, people and objects in the photo get stretched or squashed.
Untick the box only when you deliberately need an exact size and do not mind the distortion — or when you plan to crop afterwards.
Can I make an image bigger?
You can, and the 200% button does exactly that. But understand what is happening: enlarging cannot invent detail that was never captured. The browser estimates the new pixels from the surrounding ones, so the result looks softer than a photo taken at that size.
Modest enlargement — up to about 150% — usually looks acceptable. Beyond that, the softness becomes obvious.
Resize or compress?
They solve different problems. Resizing changes how many pixels the image has. Compressing keeps the pixel count but stores them more efficiently.
For a photo destined for a website, doing both usually gives the best result: resize to the size it will actually be displayed at, then run it through our Image Compressor.
Will resizing reduce the file size?
Usually, yes — fewer pixels means less data. Halving both width and height typically cuts file size to roughly a quarter.
Does this crop my image?
No. The whole image is scaled. Nothing is cut off.
Does it keep transparency?
Yes, if you choose PNG or WebP as the output format. JPEG cannot store transparency, so transparent areas become white.
Can I resize several images at once?
Not yet — this tool handles one image at a time. Batch resizing is on our list.
