All processing happens in your browser — your images never leave your device
Since JPEG does not support transparency (no alpha channel), transparent areas are filled with a white background. If you need transparency, convert to WebP instead.
JPEG uses lossy compression based on the DCT (Discrete Cosine Transform) algorithm, so there is a minor quality reduction. The default quality setting (92%) preserves excellent visual quality while reducing file size by 50-80%.
No. The conversion runs entirely in your browser using the Canvas API, so the only limit is your device memory.
Use PNG for images with sharp edges, text, transparency, or screenshots. Use JPG for photographs, gradients, and images where smaller file size matters more than pixel-perfect quality. JPG typically produces files 5-10x smaller than PNG for photographic content.
For web use, 80-85% offers a good balance. For print or archival, use 92-95%. Below 70%, compression artifacts become noticeable, especially around text and sharp edges.
PNG (Portable Network Graphics, W3C/ISO 15948) uses lossless compression with DEFLATE and supports 8-bit or 16-bit color depth plus an alpha channel for transparency. JPEG (Joint Photographic Experts Group, ISO/IEC 10918) uses lossy DCT-based compression optimized for photographic content. PNG excels for screenshots, logos, and graphics with sharp edges; JPEG excels for photographs where file size matters. Converting PNG to JPEG typically reduces file size by 50-90% for photographic images, making it the preferred format for web photos, email attachments, and social media.
