About This Tool
What is Image Format Converter?
Images come in different formats for good reasons: JPG compresses photos tightly but lacks transparency, PNG preserves transparency and handles graphics without artefacts, WebP does both while being 25-35% smaller than JPG, and GIF handles simple animations. When you need to switch formats, our free Image Converter handles the conversion cleanly without any server upload.
Upload one image or a batch. Select the target format from the output dropdown. A quality slider (for JPG and WebP) lets you balance file size against sharpness. When converting a transparent PNG to JPG - which does not support transparency - the tool fills transparent areas with white automatically.
After converting, the results panel shows each image with its new format and file size. Download individually or click Download All as ZIP for a labelled archive of the full batch. All conversion uses the Canvas API and runs entirely in your browser.
Converting to WebP is the single most effective step you can take for website image performance. At equivalent visual quality, WebP files are typically 25-35% smaller than JPG and support transparency like PNG. Every major browser has supported it since 2020. Batch convert your entire asset library in one session - select multiple files, convert all at once, and download as a single ZIP archive.

Frequently Asked Questions
Everything you need to know about Image Format Converter
JPG for photos - compact but no transparency. PNG for transparency, logos, and graphics with text - lossless but larger files. WebP for websites - 25-35% smaller than JPG at the same quality, supports transparency, supported by all major browsers since 2020. Use WebP wherever possible for web images.
JPG does not support transparency. The tool fills transparent areas with white automatically. To preserve transparency, convert to WebP or PNG instead.
Transparency is fully preserved. WebP supports an alpha channel just like PNG. This is one of the main reasons to prefer WebP over JPG for images with transparent backgrounds.
For photos at quality 85-90, quality loss is imperceptible. Text-heavy images and graphics with sharp edges may show compression artefacts - keep those as PNG or WebP. Once saved as JPG, some data is permanently discarded - always keep your original PNG as a backup.
At equivalent visual quality, WebP is 25-35% smaller than JPG. It also supports transparency (like PNG) and animation. All major browsers have supported WebP since 2020. Switching to WebP is one of the fastest wins for improving page speed scores.
Never. All conversion uses the Canvas API and runs entirely in your browser. No file data is sent to any server at any point.
