Help & Frequently Asked Questions
How do I print a letter-sized (8.5" x 11") shipping label on a 4x6 thermal printer?
Most shipping platforms (like eBay, Etsy, or USPS) generate labels in a standard PDF document designed for desktop printers. To print them on a 4x6 thermal printer, you need to crop and rotate them. Simply drop the PDF file here, and Label4x6 will auto-detect the label, crop out the white margins, rotate it to portrait, and center it with print-safe margins.
Is it safe to upload my shipping labels to this tool?
Yes, 100% safe. Unlike other online conversion tools that upload your files to external cloud servers, Label4x6 runs entirely client-side. The PDF rendering, cropping, and rotation occur strictly in your local browser window. No file data, tracking codes, or personal addresses are ever sent over the network.
Why was the border of my shipping label getting cut off?
Thermal printers require a small physical non-printable margin on the edges of the roll. If your label crop is too tight, the printer will clip the border or the barcode edges. Label4x6 automatically adds a clean 40px/60px print-safe padding around your cropped label to guarantee perfect print margins every time.
Does this tool support multi-page PDFs?
Yes. If you upload a PDF with multiple pages (for example, containing a packing slip and a shipping label), our smart dual-axis barcode scanning algorithm scans all pages in milliseconds, identifies the page containing the actual barcode, and opens it directly in the editor.
