No. This tool uses the HTML5 Canvas API entirely in your browser. Your image is never uploaded to any server. Everything — resizing, compressing, and converting — happens locally on your device.
What is the best format for web images?
WebP is the best choice for web use — it produces smaller file sizes than JPG at the same quality, and better compression than PNG while supporting transparency. All modern browsers support it. Use PNG only when you need lossless quality or transparency for logos and icons.
What quality setting should I use?
For web images, 75–85% quality gives an excellent balance of file size and visual quality. For print or archival purposes, use 90–100%. Values below 60% produce noticeable artifacts. WebP format at 80% quality typically produces files 30–50% smaller than JPG at the same quality.
What is an OG Image?
An Open Graph (OG) image is the preview image shown when you share a link on social media platforms like Facebook, LinkedIn, and Twitter/X. The recommended size is 1200×630px. Every webpage should have one — use the preset above to create one from any photo.
