Yes — completely free. All core features including label cropping, SKU detection, and PDF export are free with no limits, no registration required, and no hidden costs. We may introduce optional premium features in the future, but the core tool will always remain free.

No. All PDF processing happens entirely inside your browser using PDF.js. Your files never leave your device. We have no technical ability to read or store your label content. This was a deliberate design decision to protect your customers' shipping data.

Smart crop works by detecting non-white pixel boundaries. If your labels have very little whitespace, coloured backgrounds, or are scanned images, try switching to "Half – Top" or "Half – Bottom" mode in the Crop Method dropdown. You can also adjust the padding value in the Settings tab. If the issue persists, please contact us with a sample (redact any personal data) and your browser version.

SKU detection relies on PDF text layers. If your label PDF was generated from a scan or as an image, there may be no machine-readable text for us to extract. Try opening your PDF in a viewer — if you can select/copy text, SKU detection should work. If not, the PDF is image-only and SKU extraction isn't possible without OCR.

eCropper works best on modern Chromium-based browsers (Chrome, Edge, Brave) and Firefox. Safari on macOS and iOS is supported but may have minor differences in PDF rendering. Internet Explorer is not supported. We recommend keeping your browser up-to-date for the best experience.

Yes, eCropper is mobile-responsive and will work on Android and iOS browsers. However, for best performance with large PDFs (50+ pages), a desktop or laptop computer is recommended as mobile devices have more limited memory and processing power.

Absolutely — we love feature requests! Use the contact form above, select "Feature Request" as the topic, and describe what you need. Platform requests are especially welcome. Our roadmap is heavily influenced by seller feedback.
