Edit Image Tools
Resize, crop, rotate, flip and watermark your photos privately in your browser.
Most image editing is not retouching — it is one specific, boring change: make it fit the size a form demands, crop off the left third, straighten a photo the phone rotated wrongly, put a watermark on it before sending it to a client. Opening a full editor for that is overkill. Each tool below does one of those jobs and hands the file straight back, with the original untouched on your disk.
Which editor do you need?
- Resize Image
- An upload limit, a print size or a layout needs specific pixel dimensions.
- Crop Image
- You want to cut away part of the frame or hit an exact aspect ratio like 1:1 or 16:9.
- Circle Crop Image
- You need a round profile picture with a transparent corner, not a square one.
- Rotate Image
- A photo imported sideways, or a scan came in 90 degrees off.
- Flip Image
- You need a mirror image — common for selfies where text reads backwards.
- Add Watermark to Image
- You are sending proofs or drafts and want your name visibly on them.
- Blur Image
- A face, a licence plate, a name badge or an address needs to be unreadable before you publish.
- Pixelate Image
- You want the same censoring effect as blur but with the blocky look people recognise as deliberate.
- Brightness & Contrast
- A photo is too dark, too flat or too washed out and needs a quick correction rather than a full edit.
- Round Image Corners
- You want a soft-cornered card or thumbnail without doing it in CSS.
- Add Border to Image
- A light image disappears against a white page and needs a frame around it.
- Grayscale Image
- You want a black-and-white version, often for print or a muted background.
- Image Color Palette
- You want the dominant colours out of a photo as hex codes, to build a design around it.
- Meme Generator
- You want the classic top-and-bottom caption on an image without an app.
Resize and crop are not the same thing
Resizing keeps the whole picture and changes how many pixels it is made of — everything stays in frame, just smaller or larger. Cropping keeps the pixel density and throws away the parts of the frame you cut off. If a form asks for a 400x400 image and your photo is 4000x3000, resizing alone cannot get you there without squashing it: crop to a square first, then resize the square to 400x400. Enlarging is the one direction that never really works — a 200px image scaled to 2000px has no extra detail to reveal, only bigger, softer pixels.
Blurring a face is safer than covering it, but only if you blur hard enough
Drawing a black box over a face is reversible only if the box is a separate layer — flattened into a JPG it is genuinely gone. A light blur, on the other hand, can sometimes be partially undone, and pixelation at a large block size is generally the stronger choice for text like licence plates and account numbers. Whichever you pick, do it before you publish and re-check the exported file, not the preview: the export is what other people receive. And remember that a photo carries more than what is visible — strip the EXIF too if location matters.
Every edit here is destructive, so keep your original
These tools produce a new file for you to download; they never overwrite what is on your disk. That is deliberate, but it also means there is no undo history once you close the tab. If you are going to make several changes to the same photo, do them in one sitting and keep the untouched original somewhere safe, the same way you would with any export from a desktop editor.
Frequently asked questions
Do these tools upload my photos anywhere?
No. Every edit runs inside your browser tab using the standard Canvas API. The image is read from your disk into the page, changed in memory, and handed back as a download — it never reaches a server, so there is nothing stored and nothing to delete.
Can I edit several images at once?
Many of the tools accept multiple files and apply the same change to each — useful when a whole folder of photos needs the same resize or watermark. Tools that need you to position something by hand, like crop, work on one image at a time.
Will editing reduce the quality?
Cropping, rotating by 90 degrees and flipping are lossless operations on the pixels that remain. Resizing down discards pixels by definition. Saving the result as JPG re-compresses it, so if you plan several rounds of edits, work in PNG and convert to JPG only at the end.
Does the round crop keep a transparent background?
Yes, as long as you download it as PNG or WebP. JPG has no transparency, so a circle-cropped image saved as JPG gets solid corners instead.
