Convert multiple images at once. Local processing: your files are not uploaded to any server.
Converting an image is more than changing an extension. Each format has a purpose: quality, file size, transparency, compatibility, and how text and edges render can differ significantly between JPG, PNG, and WEBP.
JPG uses lossy compression: smaller files, but may introduce artifacts (especially on text and sharp edges). PNG is lossless and supports transparency: great for graphics and screenshots. WEBP often reduces size while keeping good quality.
| Scenario | Recommendation | Why |
|---|---|---|
| Sharing photos | JPG or WEBP | Smaller files, acceptable quality loss |
| Logos and graphics | PNG | Clean edges, no compression artifacts |
| Text screenshots | PNG | Crisp, readable text |
| Website images | WEBP | Best performance and quality balance |
| Print production | PNG or TIFF | Maximum quality preservation |
Use PNG when you need repeated editing without quality loss, when working with transparency in an editor, or when images contain text, UI elements, diagrams, or thin lines. Note: converting JPG to PNG does not restore already-lost quality — PNG will perfectly preserve the current state, including any existing artifacts.
Select or drag up to 20 images, pick an output format, click Convert, and save the results. The entire process runs locally in your browser using the Canvas API. Files are never uploaded to any server. Original files remain unchanged on your device.
When converting multiple files, all images use the same output format and quality settings. If you need different settings for different images, process them in separate batches. Large images may take a moment to process on older devices.
