OhoTool is a free online toolkit of 270+ browser-based utilities for
everyday document, image, and developer tasks — with no sign-up and no
software to install.
Most tools run entirely client-side in the user's browser, so files are
processed on the user's own device and never uploaded to a server. That
makes OhoTool a practical fit for teams handling contracts, invoices,
ID documents, or other sensitive material that shouldn't be sent to a
third-party server just to be converted.
Core capabilities include:
• PDF tools — convert to and from Word, merge, split, compress, and edit
• Image tools — convert formats, resize, crop, compress, remove
backgrounds, upscale, and extract text via OCR
• Developer utilities — JSON, JWT, hashing, regex, cURL-to-code,
formatters, and dozens more
• AI tools — Chat with PDF, writing assistants, and an AI Mock
Interview and Resume Reviewer
• Everyday tools — QR code generation, calculators, and unit converters
OhoTool is free and ad-supported. An optional Pro plan removes ads and
adds unlimited AI usage, advanced server-side document conversion, bulk
processing, dynamic QR codes with scan analytics, and a developer API.
Tools can also be embedded on other websites as widgets.
