Thermal printer logo size guide
Thermal printers print only black dots, so artwork must be pure black and white at the printer's exact pixel width. This tool sets both for you.
| Paper width | Canvas size | Best for |
|---|---|---|
| 2-inch | 384 × 200 px | Narrow receipts |
| 3-inch | 576 × 200 px | Wider receipts |
Who is this tool for?
Shop owners, billing-software developers and anyone who needs a clean header image on 2-inch or 3-inch receipts without installing software.
Tips for sharper prints
- Start with a simple, high-contrast image, because fine gradients and tiny details turn to noise in black and white.
- Keep text large and bold enough to stay readable after conversion.
- Use the bill preview to check the result on a receipt before exporting.
- Scan every QR code and barcode from a test print before using it.
Which file format should I export?
Pick TRU when your printer expects TRU files, and use BMP, PNG or JPG when you need a standard image file.

Questions & answers
Frequently asked questions
Answers about formats, printer sizes, tools, export and privacy.
What is Logo Utility Plus?
Logo Utility Plus V.1.1 is a free online thermal logo studio. It converts any image into crisp 1-bit black-and-white artwork for receipt, label and POS thermal printers, and saves it as TRU, BMP, PNG or JPG.

You can open JPG, PNG, GIF and TRU files up to 5 MB. Drag and drop, click to browse, or paste an image straight from your clipboard.
Which printer sizes are supported?
Both 2-inch (384 x 200 px) and 3-inch (576 x 200 px) thermal printers. You can also set a custom export width and height with an aspect-ratio lock and a one-click reset to printer size.
How do I convert an image to monochrome for a thermal printer?
Open your image, choose 2-inch or 3-inch, then adjust Contrast. Use the Smart tab for Auto contrast, Remove background, Clean specks, Sharpen or Line art, and check the live Preview against the Original.
What can I change in the Adjust tab?
Contrast slider, Invert, Stretch to fill, Zoom in, Zoom out and Crop. Crop lets you drag a region directly on the preview.
Can I add text to my receipt artwork?
Yes. Open the Text tab, click the preview and type directly on the artwork. Pick a font, size from 12 to 80, and Bold, Italic, Underline or Strikethrough. Drag text to move it.
Which shapes can I draw?
Rectangle, triangle, circle, oval, line and four arrows (up, down, left, right). Choose line width, solid, dotted, dashed or dash-dot styles, and round the corners.
Can I place a QR code or barcode on my design?
Yes. The QR PRINT and BARCODE tabs place codes on the preview. Each has a thermal analysis and an Auto Optimize button so the code stays scannable after 1-bit conversion.
What do the Smart tools do?
Auto contrast, Remove background, Clean specks, Sharpen, Line art, Thicken, Thin, Outline, Fill holes, Merge border colour, Flip horizontal, Flip vertical, Rotate 180 and Center.
What is Bill Preview?
The PREVIEW button shows your design on a 2-inch or 3-inch receipt. You can refresh it and merge the artwork background with the receipt colour for a seamless print.
What are Thermal Tools?
A diagnostic panel (Ctrl+Shift+T) that runs analysis on your artwork and includes a DPI calculator for 203, 300, 305 and 600 DPI printers.
What is a TRU file and how is it named?
TRU is the printer-ready format. Files use fixed printer names such as T2INCH_1.TRU, and you pick a slot from 1 to 9 when saving.
Can I undo mistakes or start over?
Yes. Use Undo (Ctrl+Z), Reset to clear all edits, Create new for a blank project, or Clear All to remove everything.
Does it work on mobile and tablets?
Yes. The layout is fully responsive and touch friendly, with a fullscreen mode for the studio and four themes: dark, light, ocean and ember.
Is my image uploaded to a server?
No. The studio runs in your browser, so your image stays on your device.
