meraSaaS - Useful tools without another subscription — all local

Hey Product Hunt 👋 This started from a small, recurring annoyance: doing some one-off admin — merge a couple of PDFs, make a passport photo the right size, generate an invoice — and having to upload personal documents to a random website to do it. For a thirty-second task, that always felt like the wrong trade. meraSaaS is 26 of those tools, and every one of them runs in your browser tab. The files are processed locally in plain JavaScript (pdf-lib, pdf.js, the Canvas API), so nothing is uploaded and nothing is stored on our side. If you don't believe it, turn your wifi off and watch a tool still work. There's deliberately no AI in it. These are deterministic tasks: a merged PDF should come out the same every time, not "mostly right." No models, no credits, no surprises. What's in it: PDFs (merge, split, compress, sign, reorder, watermark), photos (passport/visa sizes, background removal, resize/convert/crop), invoices/receipts/quotes/timesheets, a few calculators (GST/VAT, mortgage, rental yield, compound interest), QR codes, and OCR. 10 are free with no account. The rest are $7/month, cancel anytime. It's built for individuals and freelancers doing occasional admin, not for agencies. Happy to answer anything — and genuinely keen to hear which everyday tool you wish ran locally instead of on someone's server.
