About SellersPlaza

Why this exists

SellersPlaza was started by a small independent team that has spent time on the other side of a dispatch table - packing orders, printing labels, and discovering at 11pm that the printer is out of ink again. The shipping label cropper was the first tool because it solves the problem we personally hit first: every Indian marketplace hands you an A4 PDF with a label on the top half and a tax invoice on the bottom, and nothing in that file is shaped like the 4x6 label you actually want to print.

There were already tools for this. What bothered us was how most of them worked. You upload a PDF full of your customers’ names, phone numbers and home addresses to a server belonging to someone you have never heard of, and a privacy policy - if there is one - tells you what happens next. Then an algorithm guesses where the label ends, and when the marketplace changes its template the guess quietly starts cutting barcodes in half.

We thought both of those were solvable, so we built the version we wanted to use.

The privacy-first part is architectural, not a promise

SellersPlaza is a static website. There is no application server, no database, no upload endpoint and no account system. When you open a PDF in the cropper, your browser reads the file from your own disk, renders the preview with pdf.js, and rewrites the page boxes with pdf-lib - all on your device. The finished file is handed back to your downloads folder. At no point does a byte of it travel across the network, because there is nowhere for it to travel to.

You do not have to take our word for it. Open your browser’s developer tools, switch to the Network tab, and crop a file: there is no upload request. Or load a tool page, turn off your internet connection, and crop anyway - it still works, because even the pdf.js worker is served from this site rather than a third-party CDN. A tool that keeps working offline is a tool that is not sending your data anywhere.

Why the crop box is manual

Automatic cropping is the obvious feature and we deliberately did not lead with it. Marketplace label layouts change - Amazon India alone ships several templates across Easy Ship, Self Ship and FBA - and an auto-crop that assumes a fixed split fails silently when they do. It does not throw an error; it just clips the bottom of an address or half a barcode, and you find out at pickup.

A crop box you can see and drag has no such failure mode. Presets give you the right starting position for your marketplace, and adjusting when something looks off takes about five seconds. We would rather ship the reliable version.

How the site is paid for

The tools are free with no limits, no watermark and no paid tier. Hosting a static site costs very little, and the site is supported by advertising placed around the content. Ads are never placed inside the cropper, never styled to look like tool buttons, and never allowed to overlap the crop area. If a section is an advert, it is labelled as one. We do not sell data - we do not have any to sell.

What is next

The label cropper cluster came first because it is the most immediate daily pain. The roadmap from here is more of the same kind of thing - small, exact, browser-side tools that replace a spreadsheet you rebuild every month:

• Marketplace fee calculators, per platform and per category
• Profit and pricing calculators that account for commission, shipping and GST
• Return and RTO cost estimators
• Barcode and SKU label generators
• More marketplace crop presets as sellers ask for them

If a tool would save you real time each week, tell us. Requests from people actually running stores are how we decide what to build.

Get in touch

Bug reports, marketplace layouts we handle badly, and tool suggestions are all welcome. Email support@sellersplaza.com or use the contact page. If you are reporting a cropping problem, tell us the marketplace and roughly where the label sits on the page - please do not send us a real label PDF, since it contains a customer’s address and we have no wish to hold it.

Independence

SellersPlaza is not affiliated with, endorsed by or sponsored by Meesho, Flipkart, Amazon, Shopsy, GlowRoad, JioMart, Snapdeal or any other marketplace. We name them because sellers search for them by name; all trademarks belong to their respective owners. Nothing here gives you access to a seller account, and no marketplace credentials are ever requested.
