Getting an image into the right shape is usually a combination of small jobs: make it smaller, cut away the edges, turn it the right way up, then maybe put a frame around it. The tools on this page each do one of those jobs well, and they all run inside your browser, so your photos are never uploaded.
Resize, crop or both?
Resizing changes how many pixels the whole picture has. Nothing is cut off; the image just gets smaller or larger, and with the aspect ratio locked it keeps its proportions. Cropping removes part of the picture to change what is in the frame or its shape — a square from a landscape photo, a 16:9 banner from a tall one. If you need a specific shape and a specific size, crop first to get the shape, then resize to get the exact dimensions.
| You want to | Tool |
|---|---|
| Make a photo a set number of pixels wide | Resize Image |
| Set a photo to 300 DPI, or to the size it should print at, without touching the pixels | Change Image DPI |
| Cut out a square, a banner or an exact area | Crop Image |
| Make an animated GIF smaller or larger and keep it moving | Resize GIF |
| Cut an animated GIF to a square or any box, without re-colouring it | Crop GIF |
| Make a round profile picture with a transparent background | Circle Crop Image |
| Fix a sideways or crooked photo | Rotate Image |
| Put a coloured frame around a picture | Add Border to Image |
| Cut one image into a 3×3 grid or carousel strips | Split Image Into Grid |
| Put several images side by side or in a grid | Combine Images |
A sensible order of operations
When an image needs several changes, the order matters for quality. Rotate and crop first, while you still have all the original pixels to work with. Resize next, so the final dimensions are exact. Compress last, because every later edit would otherwise re-encode an already-compressed file and add more loss. After each step, the result can be passed straight to the next tool without downloading it first.
Exact sizes for social media
If the target is a platform rather than a number of pixels, start from the social media image sizes page instead. Those tools already know the dimensions each platform expects and let you position the crop around what matters in the photo.
Resizing throws pixels away; upscaling invents them
Making an image smaller is a genuine operation: the software averages groups of pixels into fewer pixels, and the result is sharp because all the detail was already there. Making an image bigger is guesswork — there is no extra detail to find, so the software interpolates, and the result is softer than the original no matter which tool you use.
This matters when a form asks for a minimum size. Enlarging a 600 px photo to 1200 px will satisfy the pixel count and fail the eye; going back to the original file, or taking the photo again, is the only real fix. Any tool promising to “enhance” beyond the source is guessing, however convincing the marketing.
Order of operations, and what each tool decides
- Crop first, resize second. Cropping changes what is in the frame; resizing changes how many pixels describe it. Doing it the other way round wastes resolution on parts you are about to remove.
- Aspect ratio is a choice, not a detail. Fitting a 4:3 photo into a 1:1 slot either crops it or adds bars. Deciding which, deliberately, is usually the difference between a good and an odd-looking result.
- Rotate before cropping, so the crop frame lines up with the picture you actually want.
- Compress last. File size follows from dimensions, so settle the pixels before chasing kilobytes — on a 15-megapixel photo, resizing to 2048 px cut the file by 78% on its own.
Nothing is uploaded
Every tool here processes the image on your own device. There is no account, no watermark and no file size limit beyond what your device can handle.
