JPEG (JPG) uses lossy compression optimised for photographs and images with smooth colour gradients. It achieves very small file sizes at the cost of slight quality reduction — invisible at quality 85+. PNG uses lossless compression and supports full transparency, making it the right choice for logos, UI elements, screenshots, and anything with hard edges or text.

Frequently Asked Questions
Everything you need to know about this conversion tool.
You can convert to JPG, PNG, WebP, GIF, BMP, TIFF, ICO, and AVIF. The available output formats depend on your input file type.
Converting to lossless formats like PNG or BMP preserves full quality. For JPG and WebP you can set quality 1–100; we default to 90 for near-lossless results.
Yes — transparent areas are filled with a white background when converting to JPG since JPEG does not support alpha channels.
Free conversions support files up to 100 MB. Most DSLR RAW exports and high-res scans fall well within this limit.
Uploaded files are stored temporarily in a sandboxed folder and deleted automatically after 2 hours. We never share or analyse your images.
WebP images are typically 25–35% smaller than equivalent JPEGs at the same visual quality, making them ideal for improving website load times.

Complete Guide to Image Format Conversion
Choosing the right image format can reduce file sizes by 60%, improve page speed scores, and ensure your visuals display correctly on every platform. Here is everything you need to know.
JPEG vs PNG: When to Use Each
Why WebP Is the Modern Standard for the Web
Google developed WebP to offer the best of both worlds: lossy compression 25–35% better than JPEG and lossless compression 26% better than PNG. It also supports animation and transparency. All modern browsers support WebP, and frameworks like Next.js and Nuxt automatically serve WebP when available. Switching your website images to WebP is one of the highest-ROI performance improvements available.
TIFF and BMP for Professional Workflows
TIFF (Tagged Image File Format) is the archival standard for print production, scanning, and professional photo editing. It supports multiple colour spaces (RGB, CMYK, LAB), 16-bit depth, and embedded ICC profiles. BMP is an older Microsoft format storing raw uncompressed pixel data — rarely used for web but still common in legacy Windows applications and certain industrial imaging systems.
ICO Files and Favicons
ICO is a container format that stores multiple image sizes (16×16, 32×32, 48×48, and optionally 256×256) in a single file. Modern favicons use a 32×32 PNG linked in the HTML head, but IE and some RSS readers still require a true .ico file at the website root. Our converter creates multi-resolution ICO files from any image source.
How to Choose the Right Output Format
Use WebP for all web images where possible. Use JPG when sharing photos via email or social media for maximum compatibility. Use PNG for anything with transparency, text, or sharp edges. Use TIFF for print and archival. Use ICO for favicons. Convert GIF to WebP to cut animation file sizes by 50–80%.
