Bulk QR Code Generator
Generate hundreds of QR codes from Excel or CSV at once
What is Bulk QR Code Generator?
Bulk QR Code Generator turns a list into many QR codes in one go. Enter one URL or line of text per row, or upload a CSV or Excel (XLSX) file; example files show the expected layout. Generate the batch and download every code in a single ZIP file.
You can choose foreground and background colours, an image size from 200 to 600 pixels, PNG or SVG output and a filename prefix. Pro users can also add a logo or background image. The codes are static: they do not expire, have no scan limit, and can be used commercially. For print, SVG is recommended.
The free plan makes up to 50 QR codes per batch; the Professional plan allows up to 1,000 per batch. Downloading the ZIP needs a free account. Chrome and Edge extensions are available. Typical uses are product and asset labels, event tickets, classroom handouts and printed marketing material.

For every one person that was answering the quiz, three were going directly to the App Store. We studied with a lot of math and rigor the correlation between those that were coming through our happy path and what was happening outside it, and those ratios were very very tight every time we had a new winning creative.
Correlate quiz-path metrics with direct App Store installs to scale spend confidently when blind
Ladder discovered that 3x more users went directly to the App Store than completed the web quiz funnel — invisible in tracking data. Stewart's solution: rigorously validate the ratio between tracked (quiz) and untracked (direct App Store) installs across multiple creative changes and budget shifts. Once the parallel movement was confirmed as stable, quiz-path metrics became a reliable proxy for total business impact.
It used to be the marginal cost of serving a user subscriber for most consumer apps was close to zero. But now with these AI powered products and features that's no longer true because you do have the underlying compute costs to support the AI features.
AI apps need tiered pricing — compute costs eliminate the zero-marginal-cost software model
The economics of subscription apps changed fundamentally with AI. Duolingo Max, Perplexity Pro, Claude Pro — the pattern is consistent: a free or basic tier without full AI access, and a premium tier for the complete AI-powered experience. Carter argues this structure is necessary for AI apps to protect margins, and that consumers are increasingly receptive because they understand AI compute costs after watching ChatGPT charge $20/month. Bootstrapped and early-stage founders must be especially conscious of this — unlimited AI features at a flat monthly price is often unprofitable.
There's a play for whatever you're stuck on.
