A platform of focused local tools
Each published tool has its own page and works in your browser. The site is delivered as static HTML and assets, without a processing server or a user account.
The nine image tools accept static JPEG, PNG, WebP, supported static AVIF and uncompressed BMP; they export PNG, JPEG or WebP. Image-to-PDF accepts JPEG, PNG and WebP. Images to PDF combines images into a real PDF document. PDF merge and split organize existing unencrypted PDFs. QR tools create text, URL or Wi-Fi codes and read one code from an image. Text tools count Unicode characters and words or convert case; these tasks remain local. Input and processing limits keep work bounded, but do not guarantee compatibility with every device.
Four readable language versions
English, simplified Chinese, traditional Chinese and Japanese each have fixed URLs and complete built-in content. The root entry chooses from the browser’s exposed language preferences, while a direct language URL always stays in that language.
A language switch keeps the same page. Existing input is cleared after your confirmation because language changes leave the current in-memory tool workspace.
Understand the limits
The tool does not promise lossless compression, preserved metadata or that every target can be reached. Browser encoders can produce different results. Save your original and inspect the output before relying on it.
