About opnai

opnai is a collection of free online tools for working with images, audio and documents. Open a page, add a file and get a result: no account, no watermark and no paid plan.

The AI tools, such as background removal, image upscaling, photo restoration, text recognition and speech, run on our own GPU server. The converters and the face blur tool run entirely in your browser, so those files never leave your device.

Principles

• No account, no watermark: every tool works straight away and results are yours to use.
• Private by design: we do not log the content of your files, we do not train AI models on them, and uploads and results are deleted automatically after 24 hours.
• Honest about limits: every tool page explains what it does, how to use it and where it falls short. AI results can be wrong, so check them before you rely on them.

What you can do

• Image: remove a background, upscale an image, compress and resize pictures.
• Photo AI: restore old photos, colorize black and white photos, remove objects, generate alt text.
• Create: infographic maker, poster generator, animated slide deck maker, motion graphic video maker.
• Audio: turn audio into text, turn text into speech, generate subtitles.
• Document and OCR: extract text from an image, convert a JPG to Word.
• Converters: HEIC to JPG, WebP to PNG, AVIF to JPG and more. Blur faces works in the same way, locally in your browser.
