Many small tools, one website.
Organize PDFs, compress images, edit subtitles, visualize audio, and clean up text. Useful tools in one place, with no site account.
Most tools process locally. AI image generation sends prompts to your provider; selected online voices may send text to a speech service.

Barcode Generator
Draw EAN, UPC, Code 128, GS1-128 and nine more barcode formats. Check digits are verified as you type and a wrong one is fixed in one click; download SVG or print-ready PNG.

Subtitle Studio
Edit SRT and WebVTT text and timing, shift the whole timeline, and check overlaps before exporting. Works with existing subtitles; no automatic transcription.
- Audio
Audio Level Studio
Adjust gain, normalize sample peaks and add fades to clips up to three minutes. Export WAV locally; sample-peak normalization is not LUFS loudness matching.

Clear about where the work happens.
- 01
Most work stays on your device.
PDF, image, media and text utilities process your inputs locally. AI image generation and selected online speech voices use external services.
- 02
No site account.
Open a tool and get started. Your language and recent tools stay in browser storage. External AI providers require their own credentials.
- 03
One job per tool.
The site interface and local tools are free. Remote image generation may consume paid credits; provider limits and device limits still apply.
- 04
Open to inspection.
You can watch every network request in your browser's developer tools. Libraries, fonts and some models need network downloads, so local processing does not mean every tool works offline.
Before you open a tool.
- Are my files uploaded?
- Most tools — PDF, image, media and text — process your files on your device without uploading them. The exceptions are stated on each tool: AI image generation sends your prompts and settings to the provider you choose, and an online speech voice you select may send text to a speech service.
- Do I need an account?
- No site account is needed. Your language and recently used tools are kept in your browser's storage. The two AI image tools need your own provider API key.
- Is it free?
- The site interface and the local tools are free. AI image generation uses your own provider credentials, so the provider's credits, charges and limits apply.
- Does it work offline?
- Not always. Libraries, fonts and some models are downloaded when a tool needs them, so offline availability depends on the tool and on what your browser has cached. Remote features always need a connection.
- How many tools are there?
- 72 tools in 8 categories, each focused on one job. The directory above lists every one of them.
- Which languages are supported?
- The interface is available in English, Korean and Japanese. Pick a language once and the tools open in it.
- How can I check what a tool does?
- Open your browser's developer tools and watch the Network tab while a tool runs: a local tool downloads pages, libraries, fonts or models, not your files. The tools are plain JavaScript, so you can read their code too.
Most tools want to know you. This one doesn't.
Email, card details, habits: small utilities ask for a lot. Reordering pages in a PDF shouldn't require any of that.
Most tools handle your files on your device. The exceptions are explicit: image generation uses a remote API, and online speech voices may send text to a speech service. The tools ship as plain JavaScript, and you can inspect their code and network requests yourself.
