Questions
Are my files safe? Yes. Every tool runs inside your own browser — your PDFs and photos are never uploaded to any server, so customer addresses and invoices stay on your device.
Will barcodes still scan after cropping a label? Yes. Labels are cut out of the original PDF, not turned into a picture, so barcodes and QR codes stay perfectly sharp.
I don't have a thermal printer. Can I print on A4? Yes — in a label crop tool choose A4 sheet — 2 labels side by side . Cut along the light dashed lines.
The label box isn't exactly right. Drag the blue box, or its round corners, to exactly the area you want. The same area is used for every page. Any Label Crop works for any courier.
Is there a limit? Up to 100 MB per file and 1,000 pages. Very large files depend on your phone or computer's memory.
Does it cost anything? No — free, no sign-up, no watermark added to your files.

Choose how strongly to compress. Basic keeps text sharp and selectable. Strong is best for scanned documents and photos — pages become images, so text can no longer be selected.
