Everything runs in your browser. The original, uncropped image is never sent to a server either.
MamePress cuts a picture down to the part you want to keep. Drag a frame over it, lock the frame to a ratio, or type its size in pixels. What sets it apart is where that happens: the whole job runs inside your browser. Nothing is uploaded to a server, so a private photo or a screenshot of a document stays on your device. There is no account to create, nothing to pay, and no watermark on the result.
Profile pictures, thumbnails and feed posts are shown in a frame with a fixed ratio. An image with a different ratio is cut or padded by the site that shows it, and not always where you would have cut it. Cropping to the ratio first keeps the framing yours. Press a ratio and the frame is locked to it; drag it to where it belongs.
| Ratio | Shape | Typical use |
|---|---|---|
| 1:1 | Square | Profile pictures, icons, marketplace listing photos |
| 16:9 | Wide | YouTube thumbnails, slides, desktop wallpaper |
| 9:16 | Tall | Stories, short-video covers, phone wallpaper |
| 4:3 / 3:4 | Standard | Everyday photos, pictures placed in a document |
| 3:2 / 2:3 | Camera | The usual ratio of a digital camera, 4×6 inch prints |
| 4:5 | Slightly tall | Instagram portrait feed posts (1080×1350 px) |
| 3:1 | Wide strip | X (Twitter) header images (1500×500 px) |
Two more buttons sit in front of those. Free lets you drag any rectangle, and Original keeps the proportions the picture came with. Whole image puts the frame back on the entire picture.
A dragged frame lands on a round number only by luck. Under the picture, Set an exact crop size takes a width and a height: type 1500 and 500 and the frame is exactly 1500×500 px, and with a ratio locked you only type one of them. Those pixels are cut out of the original as they are. Nothing is scaled, which is also why the numbers cannot be larger than the original. If what you want is the whole photo at a given size, such as a 4000px picture made 1080 wide, that is resizing: crop it to the shape here, then set the pixels in the image resizer.
Sometimes nothing can be cut: a full-length portrait that has to fit a square, a wide logo that has to become an icon. Switch from Crop to Add borders and choose the ratio. The picture is kept whole and borders are added above and below, or left and right, until it has that ratio. The border can be White, Black or Transparent; a transparent border is always saved as PNG.
The picture itself is neither enlarged nor shrunk, so the result is the original size plus the borders. Two limits are worth knowing. The borders go on the two sides that fall short of the ratio, not all the way round, so this is not a tool for an even frame of a set width. And the size of the result follows from the picture and the ratio; to land on an exact pixel size, save the image and then resize it.
The cropped image is saved in the format it was opened in: JPEG stays JPEG, PNG stays PNG, WebP stays WebP. HEIC becomes JPEG, and AVIF, GIF and BMP become PNG, because a browser cannot write those formats. When the format is going to change, the page says so under the size before you save. Because nothing is scaled, cropping itself does not blur anything. A PNG is written without loss. A JPEG is compressed once more when it is saved, and so is a WebP; on a photo that is hard to see, and on screenshots, text and logos it can show slightly along sharp edges. A JPEG that is saved as a JPEG keeps the print resolution (DPI) recorded in the original, so a 300dpi scan is still a 300dpi scan after it is cropped.
Are my images uploaded anywhere?
No. The cropping is done inside your browser, on your own device. Neither the original picture nor the cropped one is sent to a server; there is no upload endpoint to send them to, so there is also nothing to delete afterwards.
How do I crop a picture to a square?
Open the image and press 1:1 in the Ratio row. The frame is locked to a square and placed in the middle of the picture; drag it to the part you want and press "Download the cropped image". If you would rather not lose the edges, switch from "Crop" to "Add borders": the whole picture is kept and borders are added until it is square.
Can I crop to an exact size in pixels?
Yes. Under the picture, "Set an exact crop size" has a width box and a height box. Type a number and the frame becomes exactly that many pixels; with a ratio locked, the other box follows. The frame can be as small as 16px a side. What you type is cut out of the original pixel for pixel, with no scaling, so it cannot be larger than the original. To make the whole photo a given size instead, crop it to the shape here and then set the pixels in the resizer.
Does cropping lose quality?
The part you keep is not scaled, so it has exactly the pixels it had. What differs is the save. A PNG is written without loss, and not one pixel changes. A JPEG is compressed once more when it is saved, at quality 0.92, and so is a WebP; on a photo that is hard to see, and on screenshots, text and logos it can show slightly along sharp edges.
Can I fit a whole photo into a square or 4:5 frame without cropping it?
Yes. Switch to "Add borders" and choose the ratio. Nothing is cut off: borders are added above and below, or left and right, until the picture has that ratio. The border can be White, Black or Transparent, and a transparent border is always saved as PNG. The borders go on the two sides that fall short, not all the way round, and their width follows from the ratio rather than being typed.
Which ratios are there?
Free, Original, 1:1, 4:3, 3:4, 16:9, 9:16, 3:2, 2:3, 4:5, 3:1 are the buttons in the Ratio row. Free lets you drag any rectangle, and Original keeps the proportions the picture came with. For a shape that is not on the list, choose Free and type the width and height in pixels.
Which formats does it read and write?
It reads JPEG, PNG, WebP, AVIF, GIF, BMP, HEIC and HEIF, up to 50MB a file. A JPEG, PNG or WebP is saved in its own format. HEIC and HEIF come out as JPEG, and AVIF, GIF and BMP come out as PNG, because a browser cannot write those formats; the page says so under the size before you save. An animated GIF is read as its first frame, and the animation is not kept.
Can I crop a photo into a circle or another shape?
No. The frame is always a rectangle. For a round profile picture a square crop is usually what is needed: most sites take a square image and draw the circle themselves.
Can I crop several images at once?
No, this tool opens one image at a time. If you drop several, the first one is opened and the others are listed by name under the box with the reason they were not. The resizer and the compressor on this site work on batches of up to 30 images.
Can I crop iPhone photos (HEIC)?
Yes. HEIC and HEIF files are decoded in the browser, so a photo straight off an iPhone can be dropped in without converting it first, and the cropped picture is saved as a JPEG. There is no app to install.
To change the pixel dimensions of the cropped image, use theimage resizer. To get the file under a set size in KB or MB, there is theimage compressor, and to cut the background out of a picture, thebackground remover. All three run in the browser too.
