Fit a product photo to an exact size

Choose a product photo, pick the output size (for example 1000×1000), margin and background, then press “Fit to size”. The photo is centred without stretching, and the saved file is checked against the requested size.

How it works

The output is always exactly the chosen size (width × height in px). The photo is scaled, keeping its aspect ratio, to the largest size that fits inside the margins, and centred — never stretched or squashed.
The margin is the same on all four sides and measured from the output’s shorter side (for example 5% of 1000×1000 = 50 px). If the photo and the space have different ratios, one direction gets extra space.
A photo smaller than the space is centred at its original size by default. Allowing enlargement scales it up to fit, but quality does not improve.
The rest is filled with the background colour you choose; PNG and WebP can stay transparent. JPEG has no transparency, so it is filled with white.
The saved file is opened again and its real size is compared with the requested size; the result says whether they match.

Where the photo goes on 1000×1000 with a 5% margin (example)
Original (px)	Photo size (px)	Position (X, Y)
4032×3024	900×675	50, 162
3000×4000	675×900	162, 50
1200×1200	900×900	50, 50

Does this meet Amazon, Etsy or Shopify image rules?

Each marketplace has its own rules for main-image size, background, margins and text, and they change, so no specific marketplace is guaranteed. Check the current guidelines in your seller centre first, then enter those numbers here.

A white 1000×1000 square is a common format, not an official standard.
If a rule says how much of the frame the product must fill, adjust the margin to match.

Is my image uploaded to a server?

No. The image is opened and saved again only inside this browser. It is never sent to a server, and the work pages carry no ads or third-party analytics. When you close the page, the image and the result are cleared from memory.

Is camera information such as location (EXIF) removed?

The image is redrawn and saved through the browser's canvas, so the original camera information is usually not carried into the result. This has not been confirmed for every browser and file, so removal is not guaranteed. If the photo contains sensitive information, check the result with another tool.

Canvas toBlob (MDN): How the browser saves an image in a chosen format and quality. If a format is not supported, the real output format is checked and you are told.

CropKeep only the part of an image you need. Drag a free-form or 1:1, 4:3, 3:4 or 16:9 area, or type exact pixel coordinates, and check the real output resolution and file size before you download. Nothing is uploaded.
Target file sizeGet an image under a size limit such as 100 KB, 200 KB or 500 KB. The highest quality that fits is found automatically, and the image is scaled down only if quality alone is not enough. Processed in your browser, never uploaded.
CompressRe-save an image as JPEG or WebP at the quality you choose and see the real output size and how much smaller it got. If the result is larger, you are told. Nothing is uploaded — it all happens in your browser.
