Privacy-First Image Cropper, Resizer & Squircle Studio
Zero-upload client-side image transformation studio. Crop images with fixed aspect ratios, apply continuous Apple squircle curves or circular masks, and export high-resolution WebP, PNG, or JPEG assets without transmitting your private photos or design assets across the internet.
#How to Use This Tool
#Mathematical Formula & Standards
#Edge Cases & Technical Considerations
Preserving Alpha Transparency in Corners
When exporting circular avatars or rounded photos, JPEG format does not support transparency and will render clipped corners with a black or white backdrop. Always select WebP or PNG format with Transparent backdrop to preserve transparent corners.
High-Resolution DPI Preservation
The engine extracts pixels at natural source resolution rather than viewport display size, ensuring high-DPI (Retina) clarity remains crisp upon export.
Large File Memory Management
Images up to 25MB are handled in-memory using hardware-accelerated Canvas rendering contexts without UI stutter or server limits.
#Frequently Asked Questions
Q:Are my uploaded images stored or sent to any server?
Never. All cropping, pixel interpolation, masking, and compression execute entirely on your device via HTML5 Canvas. Zero network requests are made, ensuring complete compliance with GDPR Article 28, KVKK, and enterprise confidentiality requirements.
Q:What is the difference between a rounded rectangle and an Apple squircle?
A standard rounded rectangle consists of straight lines connected to circular arcs, creating an abrupt change in mathematical curvature where the line meets the circle. A squircle continuously shifts its curvature radius from the straight edge to the vertex, eliminating optical harshness and producing a premium visual aesthetic.
Q:Can I export images with transparent backgrounds?
Yes. When selecting WebP or PNG format and leaving the backdrop setting as Transparent, all clipped corner areas retain full alpha channel transparency.
Q:Can I use the generated CSS and SVG in my own website?
Yes. The studio provides instant copy buttons for both CSS clip-path and SVG <clipPath> definitions so you can apply the exact same squircle shape to native HTML elements.
