LabelPair only shows up when you are sharing a PDF. If the app is offering an image or a web link, look for a "Save as PDF" or "Download label" option first. In Safari, open the PDF itself, then share.
If you are sharing a PDF and still don't see it, scroll the app icons in the share sheet to the end, tap More, and turn LabelPair on.
LabelPair keeps the original page size, so the printed size is decided by your printer settings. In the print dialog make sure scaling is off, or set to 100%, and that the paper size matches the original (usually US Letter).
LabelPair expects each input page to have its label on the left half, which is how carriers and marketplaces usually generate them. If your labels are centered or on the right, the two halves will overlap. Email us a sample (with the address covered) and we will look at supporting that layout.
Yes. Every page of every PDF in the queue becomes one label. A five-page PDF counts as five labels and produces three output pages.
The last page will have one label on the left and an empty right half, exactly as it arrived. Nothing is lost.
By default the queue is cleared after each batch so the next round starts fresh. The generated PDF is kept in Recent (the clock button) for 30 days, where you can preview, print, or share it again. To keep the queue instead, open the … menu and turn off Clear Queue After Generating.
Tap Edit in the top-left corner and drag the handles, or touch and hold a row and drag it. The first label goes on the left of page one, the second on the right, and so on.
No. The app has no network access. Everything happens on your device. See the privacy policy.
Swipe left on any queued or recent item to delete it, or use Remove All in the … menu. Deleting the app removes every file it stored.
LabelPair requires iOS 26 or later on iPhone or iPad. Printing uses AirPrint, so any AirPrint-compatible printer on the same Wi-Fi network works.
