Are my images uploaded to any server during format conversion?

No! Unlike traditional online format converters, CompressTinyImage runs 100% inside your browser using HTML5 Canvas and native device memory. Your photos never touch a remote server, ensuring absolute privacy.

Which formats can I convert between?

You can convert between all major formats including WebP, JPG / JPEG, PNG, AVIF, ICO (Favicons), PDF (Single-Page Document), BMP, and GIF with zero server uploads and instant batch zip downloads.

Why should I convert my JPG or PNG images to WebP or AVIF?

WebP and AVIF images are typically 25% to 50% smaller than comparable JPEGs and up to 80% smaller than PNGs while preserving transparent backgrounds and high visual fidelity. Converting dramatically improves website load speed and Google Core Web Vitals.

How do I convert images to website Favicons (.ICO)?

Simply choose "Convert to ICO" in the Format Converter dropdown. The converter automatically generates standard multi-resolution 32-bit ICO files with transparency that work seamlessly as browser tab icons.

How do I convert images to PDF documents for official forms?

Select "Convert to PDF" in the output format selector. The converter encapsulates your high-resolution image into a clean single-page PDF document ready for uploading to school, job, or legal document submission portals.

What happens to transparency when converting PNG to JPG?

JPG does not support transparent alpha channels. When converting transparent PNG images to JPG, transparent areas are automatically blended onto a clean, solid white background.

Can I batch convert multiple images at once?

Yes! You can select or drag-and-drop multiple images simultaneously. The converter processes them in parallel and provides a single "Download All (.ZIP)" button to download all converted images at once.
