Image Resizer

Every marketplace has an image-size rule, and none of them publish it in the same words. Meesho wants white-background photos capped on the longest side, Flipkart wants a square canvas that doesn't crop your product, Instagram wants exactly 1080×1080 — and your camera shoots 4000×3000 at 6MB. This free image resizer bridges that gap in one step: drop a batch of photos, pick a marketplace preset or type exact dimensions, and download correctly sized copies — no signup, no upload, no watermark from us.

The presets are the three jobs Indian sellers actually run. Meesho listing caps the longest side at 2000px on a white background (JPEG) — big enough for zoom, small enough to upload fast, and it never upscales: a small photo stays sharp instead of getting stretched. Flipkart listing produces a 1000×1000 white canvas with your photo contain-fitted inside — the square shape catalogs expect, with letterbox margins instead of a forced crop that chops off product edges. Instagram / social gives the exact 1080×1080 square for posts and stories covers. And Custom size takes any width and height up to 8000px with a lock-aspect toggle: with the lock on, typing a width updates the height to your photo's ratio; with it off, you get the exact box with the image centred — never distorted.

Distortion is the failure mode this tool is built to avoid. Na stretch, na squash: everything uses contain-fit maths, so a 4:3 photo in a 1:1 box keeps its proportions and fills the frame up to the edges with white margins where needed. Downscaling uses the browser's high-quality canvas draw, and the white-background flatten is a real canvas composite (transparency painted white before encode) — not a filter guess. Output format follows the preset: JPEG for marketplace uploads (universally accepted, compact) or PNG when you want lossless edges for graphics.

Batch is first-class: multi-select in the file picker or drag a whole folder onto the dropzone, see live target dimensions for the selected photo, process everything in one run and pull down a single ZIP. Each result row shows original size, final size and the exact pixel dimensions so you can sanity-check against the catalog guideline before uploading. Because every step runs in your browser on canvas, a 30-photo batch finishes in seconds with no queue — and your unlisted product shots never touch a server.

Order of operations matters: edit first (crop, background, color), resize last, compress only if the platform asks. Keep masters at original resolution forever — marketplaces change their recommended sizes more often than you think, and re-exporting from a master is lossless-ish while re-resizing a resized file compounds softness. Pair this with the Image Compressor for hard size limits, the Watermark Tool for branded copies, and the Image Maker when you need a clean white-background shot to begin with.
