What is Privacy Image Studio?

Privacy Image Studio is a completely browser-based image resizer and converter. It allows you to resize images, adjust dimensions, and convert between formats like PNG, JPG, WebP, HEIC, TIFF, BMP, and SVG. All processing happens locally on your device — no files are uploaded, ensuring your privacy.

Are my images uploaded to a server?

Absolutely not. All image processing is done locally in your browser using pure front-end technologies. Your images never leave your device, providing the highest level of privacy.

What image formats are supported?

We support PNG (lossless), JPEG (lossy), WebP (modern), BMP (bitmap), TIFF (print), and also Apple's HEIC/HEIF format, as well as SVG vector graphics. You can resize and convert between these formats.

Can I resize images? How do I change image dimensions?

Yes! You can easily resize images. Choose a resize mode: scale by percentage, set width (maintain aspect ratio), set height, or free stretch. Enter your desired values and click 'Process'. All resizing is done locally.

How do I convert HEIC photos from iPhone?

Our tool natively supports HEIC/HEIF conversion. Simply upload your iPhone photos, select the output format (JPG, PNG, etc.), and optionally resize them. The conversion happens entirely in your browser.

Frequently Asked Questions (FAQ)

Why use a local image resizer?

Traditional online tools require uploading images to a server, risking privacy. Our tool runs entirely in your browser — your images stay on your device. Perfect for personal, confidential, or sensitive images.

Can I resize images? How?

Yes! Select a resize mode (percent, fixed width, fixed height, or free stretch), enter the desired values, and click "Process". The tool will generate resized images locally.

What is HEIC and why convert it?

HEIC is the default photo format on iPhones/iPads. It offers better compression than JPEG but is not universally supported. Our tool converts HEIC to JPG/PNG so you can view and use them anywhere.
