How can PixelKit Studio process files without uploading them to a server?

PixelKit Studio utilizes modern client-side WebAssembly, JavaScript libraries (pdf-lib, Tesseract.js, JSZip), and the HTML5 Canvas API. When you select a file, it is read into your browser memory and processed locally on your device CPU/GPU.

Are my files stored anywhere on your servers?

Never. Because our architecture is strictly client-side, your files never travel over a network connection to our servers. As soon as you refresh or close the tab, the memory is cleared by your browser.

Can I use PixelKit Studio offline?

Yes. Most tools (Image Resize, Format Converter, Merge PDF, Photo Editor, Watermark Remover, Passport Maker, Batch Studio) function completely offline once the page is loaded.

What are the file size and conversion limitations?

There are no arbitrary daily quotas, paywalls, or artificial limits. File processing capacity depends purely on your device memory.

How does multi-language OCR work?

The Document Scanner & OCR tool uses a browser-compiled Tesseract.js neural engine. It loads trained recognition models locally in your browser to extract text from images in English, Gujarati, Hindi, and more.

Is PixelKit Studio free to use for commercial projects?

Yes! PixelKit Studio is 100% free for both personal and commercial use with no watermarks.

How is 300 DPI metadata injected?

For PNG, the physical pixel dimension (pHYs) chunk with CRC32 checksum is directly modified. For JPEG, the JFIF APP0 marker density bytes are updated directly in browser memory.

Are my photos uploaded to a cloud server?

No. All canvas processing, resizing, and encoding occur entirely inside your browser using HTML5 Canvas & WebAssembly.

Image Resize & DPI — FAQs & Help

You have complete control: if you do not set a file size limit, high-quality rendering is maintained. If a target KB limit is set, an iterative binary search algorithm calculates the optimal quality factor locally.
