Step 2: Configure Your Label Settings
Set your size preferences, enable any enrichment features you need - free text, numbering, separators - and save your settings. They apply automatically to every label you generate from that point on.
Step 3: Generate, Download, and Print
Labels download as a PDF, ready to print on thermal or Avery stock. For custom designs, use the Label Editor to build your template once and apply it across every generation method.
Done!

Frequently Asked Questions
Everything you need to know about using Label Resizer across multiple e-commerce platforms.
Which platforms does Label Resizer support?
Label Resizer supports Amazon, Walmart, UPS, FedEx, USPS, DHL, DPD, eBay, Etsy, Mercari, Shopify, Flipkart, ShipBob, and Mercado Libre for label upload and resizing - over 100 label types across these platforms. The browser extension also adds buttons directly inside FedEx Ship Manager, UPS Shipping Manager, and Mercari.
Do I need the browser extension or can I use the web uploader?
Both methods are available and produce the same output. The extension is faster if you're working inside a supported platform - it adds a button directly to the label page. The web uploader works for any PDF from any platform, with no extension required. Both support the same enrichment features.
Can I generate labels without downloading a PDF from a marketplace first?
Yes. The spreadsheet method generates labels entirely from your own data. Download the Label Resizer template, fill in your product information, and upload - no platform PDF needed. You can also use the Label Editor to design a custom template for the output.
Can I add my logo and brand name to every label?
Yes. In the Label Editor, add your logo or brand name as a static image or text element. It prints the same on every label that uses that design - regardless of the product or platform.
Does Label Resizer support Avery sheet labels for inkjet and laser printers?
Yes. Both Avery sheet presets and custom dimensions are available for all label types. Output PDFs are formatted for A4 or letter-size Avery sheets - compatible with any standard inkjet or laser printer.
Can I integrate label generation into my own system via API?
Yes. The Label Resizer API supports product label and shipping label generation via REST calls. Your account settings apply automatically to every request. API access requires a Professional or Unlimited membership.
What barcode formats can I generate?
