Overview

Ohillo is a browser-based set of free document and code generators for invoices, receipts, QR codes, barcodes, and related business templates. The core tools are available without an account, and the site says free downloads have no watermark and run privately in the browser.

It is aimed at people who need to create a clean business document or scannable code quickly: send an invoice, print a receipt, label a product, generate a QR code, or produce other simple office documents without opening design software or spreadsheets. Pro adds features such as dynamic QR codes, bulk generation, recurring invoices, saved documents, and an API.

Core features

Invoice generation

Create invoices with business details, client information, line items, tax, discounts, notes, and a unique invoice number, then download a print-ready PDF or print it directly.

Receipt creation

Make itemized receipts for sales, rent, deposits, and other payments, with receipt numbers, payment methods, tax, and optional footer text.

Codes for products and sharing

Generate QR codes and barcodes from links, text, product data, or common barcode formats, then download PNG or SVG files.

Customization controls

Choose sizes, colors, and error-correction levels for QR codes, and upload a logo for supported tools or Pro QR options.

Browser-based workflow

Keep files private by generating them in the browser without sign-up, with no watermark on free downloads and no uploaded document data.

Pro-only extras

Upgrade to Pro for dynamic QR codes, bulk QR and barcode generation, recurring invoices, saved documents, and API access.

Practical use cases

Billing a client
Prepare a professional invoice for a client, add line items, tax, discounts, and payment terms, then download a PDF you can email or print.
Recording a payment
Create a receipt for a sale, rent payment, deposit, or personal transaction, including item lines, receipt number, and payment method.
Sharing information with a scan
Generate a QR code for a link, text, Wi-Fi login, or contact info, then export it as PNG or SVG for print or digital use.
Labeling products
Make a barcode in a common format such as UPC, EAN, or Code 128 for product labels or internal inventory use.
Higher-volume or automated workflows
Use Pro when you need recurring invoices, saved documents across devices, bulk exports, or an API for automated workflows.

Pros and Cons

Pros

Free forever tools with no account required.
Unlimited downloads and no watermark on free files.
Works entirely in the browser, which the site says keeps document data private.
Covers several common business tasks in one place, including invoices, receipts, barcodes, QR codes, quotes, estimates, purchase orders, and work orders.
Supports practical output options such as PDF for documents and PNG or SVG for codes.

Cons

The free tools are geared toward one-off creation; recurring invoices, saved documents, bulk generation, and API access require Pro.
The QR code generator is static on the free plan, so the encoded content cannot be edited after printing without upgrading.
