Fits the full photo in a square — nothing gets cropped off
Mercari's grid displays the first photo square — listings with pre-squared photos look uniform and professional. This free tool fits your full photo into a 1080 × 1080 square with a white or blurred fill — nothing gets cropped off, and nothing is uploaded to any server.
The Mercari preset is already selected. Drop, click, download, list.
On Mercari the first photo is doing two jobs at once. It is your thumbnail in search results — small, square, competing against a screen full of others — and it is the first thing a buyer sees when they open the listing. Get the framing wrong and you lose the sale in the grid, before anyone reads your description or sees your price.
The crop is the usual culprit. Phone cameras shoot 4:3, Mercari's grid shows squares, and the difference comes off the top and bottom of the frame. On a pair of trainers that is the sole and the laces; on a jacket it is the hem and the shoulders. Fitting the whole photo inside the square instead keeps the item recognisable at thumbnail size, which is the only size that matters for getting the click.
Mercari allows up to 12 photos per listing and sellers consistently do better using most of them — multiple angles, tags, and honest close-ups of any flaw. Resize the set in one pass here so the whole listing looks consistent rather than a mix of crops and orientations.
Keep text and stickers off the first image. Overlays that look like promotional badges read as spam in a grid and hurt the thing you are trying to help.
Straight off your phone is fine. Nothing is uploaded — it never leaves this tab.
Mercari's preset is 1080×1080. Your first photo becomes the search thumbnail.
White reads cleanest at thumbnail size; blur suits lifestyle shots further down the listing.
The item stays recognisable in the grid, which is the only size that decides the click.

Your first photo is a small square in a crowded grid. Fitting the entire item inside it keeps the piece recognisable at the only size that decides the click.
Phones shoot 4:3, Mercari shows squares, and the difference comes off the top and bottom — exactly where the identifying details sit.
Runs in this browser tab. Nothing is uploaded, and EXIF location data does not travel with the file.
Mercari allows 12 and sellers do better using most of them. Square the set together so the listing reads as one coherent shoot.
