Free eBay Standard Envelope Converter

eBay usually gives you a 4 × 6 inch shipping label. Some downloads are that same label centered on an 8.5 × 11 letter page, which is why printing it directly rarely lands correctly.

A standard #10 envelope is 9.5 × 4.125 inches (4⅛ × 9½). Choose Envelope Com 10 in your printer settings and print at 100% / Actual Size.

A 4 × 6 page is smaller than a #10 envelope, so most printers center the smaller page and the postage never lands in the upper right. This tool builds a true 9.5 × 4.125 page with the return address, postage, and destination already in the right places.

No. Regions are clipped from your original PDF and placed at 1:1 scale, keeping the original vector drawing. If you pick an output page too small to hold the label, the tool tells you it had to scale down.

Upload it. The converter scans the page for the 4 × 6 label and crops to it automatically. If the page is unusual, drag a box around the label yourself and continue.

Yes. Upload a multi-page PDF and every page becomes its own page in the output PDF, so you can print the whole batch in one job.

No. Fit to Page changes the physical size of barcodes and postage, which can make them unscannable. Use Actual Size / 100%.

No. The conversion runs entirely in your browser using local JavaScript. The PDF is never sent to a server, and nothing is stored after you close the tab.
