A 6 MB photo from a phone camera is fine for a frame and wrong for everything a business does with it: WhatsApp compresses it into mush, marketplaces reject it, the website loads in five seconds on a customer's 4G, and the email bounces. This resizer and compressor brings product and catalogue photos down to the right dimensions and file size for each channel — WhatsApp, Instagram, Amazon/Flipkart/Meesho, your website, GST invoices and email — in your browser, with no upload, no watermark and batch processing for a whole catalogue.
Sizes that each channel wants
| Channel | Dimensions | Target size |
|---|---|---|
| WhatsApp catalogue / status | 1080 × 1080 (square) or 1080 × 1920 (status) | Under 1 MB |
| Instagram feed / Reels cover | 1080 × 1350 (4:5) / 1080 × 1920 | Under 1 MB |
| Amazon product image | 1600 × 1600 minimum on the longest side (2000+ for zoom), pure white background | Under 10 MB, JPEG |
| Flipkart / Meesho | 1000 × 1000 or larger, square | Under 2 MB |
| Website product photo | 1200 px wide, WebP | 80–200 KB |
| Website hero/banner | 1920 × 800 | Under 300 KB |
| Invoice/letterhead logo | 600 px wide, PNG with transparency | Under 100 KB |
| Email attachment | 1200 px wide | Under 500 KB |
How to use the tool
- Drop one image or a folder of them (JPEG, PNG, WebP, HEIC from iPhones).
- Pick a preset — WhatsApp, Instagram, Amazon, website, email — or set width, height and crop (fit, fill, square) manually.
- Choose the output format: JPEG for photos, PNG for logos with transparency, WebP for the web.
- Move the quality slider; the tool shows the resulting file size live. 80–85% JPEG quality is visually lossless for products.
- Download individually or as a ZIP; file names are preserved with a suffix.
Why compression matters for sales
Page speed is a ranking factor and a conversion factor — a product page that loads in 2 seconds instead of 5 converts measurably better on mobile, which is where most Indian shoppers browse. Marketplaces and Google Business Profile also favour sharp, correctly sized images. The pairing that works for most small businesses: shoot in good daylight, remove the background with the background remover, resize here per channel, and write the caption with the social post generator. Which AI tools genuinely help a small shop with images is covered in AI for the small shop in 2026.
Practical tips
- Keep an original at full resolution; resize copies per channel.
- Marketplaces want the product filling 85% of the frame on white — crop before resizing.
- Strip EXIF (the tool does by default) so location data from your phone does not ship with product photos.
- Name files descriptively (
