Where is 150 KB the right choice?
| Form | Specification |
|---|---|
| Marketplace catalogue uploads | Most accept well above 150 KB; this is a quality choice, not a cap |
| Portals capping at 150 KB | Some state and university portals set exactly this |
| WhatsApp Business catalogue | Sends faster on a weak connection at this size |
Which photos deserve this size?
- The close-up shot in a saree or jewellery listing, where weave and stone detail decide the sale
- Catalogue images that need to survive a buyer zooming in on a phone
- Portals that state a 150 KB maximum
What does 150 KB preserve that 100 does not?

Note what changed against the smaller rungs: the pixels stay large at 1000 × 1000, and quality stays at 82. That is the trade for a product photo — you keep the resolution a buyer zooms into, and spend the file budget on holding detail rather than on shrinking the frame.
Why does texture need the extra 50 KB?
Because 100 KB is where fabric stops looking like fabric. Below roughly 120 KB at catalogue dimensions, JPEG starts smoothing the fine repeating structure of a weave — the file gets smaller by deciding the pattern is noise. On a plain-coloured garment nobody notices. On a bandhani, a kanjivaram border or a stone-set earring, the thing the buyer was looking at is what disappears. 150 KB buys that back for about 50 KB more per image.
Frequently Asked Questions
Is 150 KB better than 100 KB for product photos?
For a detail shot, yes. Fabric weave, embroidery and stone-set jewellery start to soften below roughly 120 KB at catalogue dimensions, because JPEG treats fine repeating texture as noise and smooths it. For a plain-background flat lay of a solid-colour garment, 100 KB is indistinguishable and uploads faster.
Should every image in my catalogue be 150 KB?
No. Use it for the one or two close-ups where texture is the selling point, and 100 KB for the rest. A 40-image catalogue at 150 KB each is 6 MB, which is a slow send on a weak connection and no better on the shots where nothing is being examined closely.
What pixel size should a 150 KB product photo be?
At least 1000 × 1000 for most Indian marketplaces, which is the floor Meesho, Flipkart and Amazon enforce. 150 KB is comfortable at that size — you are not trading pixels for file size the way you are on an exam photo.
Will 150 KB pass marketplace upload limits?
Comfortably. Marketplace caps are typically several megabytes, so 150 KB is well inside. The reason to compress at all is upload speed and how fast the listing loads for a buyer on mobile data, not the limit.
Is my photo uploaded anywhere?
No. Compression runs in your browser via the Canvas API and the file never leaves your device.
