Image Converter is a browser-based tool that converts image files between formats — including JPEG, PNG, WebP, GIF, and BMP — without uploading images to any server.
How it works: It loads the source image into an HTML Canvas element, then exports it as the target format using canvas.toBlob() with the appropriate MIME type. The browser's built-in image codecs handle encoding and decoding — no server round-trip, no upload, no external size limits.
When you need it: Users typically reach for Image Converter when converting a PNG screenshot to JPEG for email, transforming a WebP download to a format your app accepts, converting BMP files from older software to modern formats, or preparing images in the exact format required by a platform or API.
Key Facts
Quick reference for choosing the right output format.
| Format | Transparency | Compression | Best for |
|---|---|---|---|
| JPEG | No | Lossy | Photos, email, universal sharing |
| PNG | Yes | Lossless | Logos, UI, screenshots with text |
| WebP | Yes | Lossy + lossless | Modern web delivery |
| GIF | Yes (1-bit) | Lossless | Simple animations, icons |
Concise answers for common searches — definitions, steps, and comparisons.
At similar perceived quality on photographic heroes: JPEG baseline ~100% size reference, WebP lossy ~65–75% of JPEG bytes, AVIF lossy ~50–60% of JPEG bytes — varies by encoder and content. AVIF encodes slower in browsers; WebP has broader tooling maturity. Practical stack: export WebP + JPEG fallback via <picture> until AVIF QA passes on your CDN. PNG remains best for transparency and screenshots regardless of converter choice.
Drag and drop or click to browse. Supported input formats: JPEG, PNG, WebP, GIF, AVIF, BMP, and TIFF.
Select the target format from the dropdown: JPEG, PNG, WebP, or AVIF. WebP is recommended for web use.
For lossy formats (JPEG, WebP), use the quality slider to balance file size against visual quality.
Click 'Download' to save the converted file. Processing runs entirely in your browser.
Common real-world scenarios where this tool saves time.
Convert JPEG or PNG images to WebP or AVIF for significant file size savings and better Core Web Vitals performance.
Convert images to a format accepted by a specific platform, CMS, or design tool that restricts input types.
Convert JPEG (no transparency) to PNG or WebP when you need a format that preserves transparent backgrounds.
Convert large image libraries to WebP to reduce CDN bandwidth costs without replacing your design originals.
Step-by-step chains that connect related tools for common tasks.
JPEG suits photographs; PNG suits transparency and sharp UI; WebP suits modern web delivery. Converting does not recover quality lost in a prior JPEG save.
Input
hero-banner.jpg · 480 KB · 1920×1080 · Quality: 85%Output
hero-banner.webp · 310 KB · 1920×1080 (35% smaller)WebP achieves equivalent visual quality at smaller file sizes. A 35% reduction on a hero image means 170 KB less data per page load — meaningful for Core Web Vitals and mobile users on slower connections.
Input
product-photo.png · 2.1 MB (no transparency needed)Output
product-photo.jpg · 320 KB at 85% quality (85% smaller)PNG is lossless — great for transparency but unnecessarily large for photographs. Converting a product photo to JPEG at 85% quality reduces it by 85% with no perceptible quality difference in the final image.
| Related tool | Use this tool when | Use related tool when |
|---|---|---|
| Image Compressor | You want to switch to a more efficient format (JPEG → WebP → AVIF) to get better compression at the same quality level — the format change itself reduces file size by 25–50% without touching quality settings. | The image is already in the right format but still too large — you need to reduce file size by adjusting encoding quality within the same format. |
| Image Resizer | The image dimensions are already correct for your use case and you only need to change the format for compatibility or performance. | The image is physically too large in pixel dimensions and must be scaled down before converting — resize first, then convert for the smallest possible output file. |
| PNG to JPG Converter | You need to convert between multiple formats (e.g. BMP → WebP, HEIC → PNG) or need AVIF output — this tool covers all format pairs. | You specifically need the PNG to JPEG conversion and want a focused single-step tool with no other options. |

No. Conversion runs in your browser using the Canvas API. Your images never leave your device.
WebP is the best choice for most web use — 25-35% smaller than JPEG at the same quality, with broad browser support (all modern browsers). AVIF is even smaller but has slightly less compatibility.
No. PNG is lossless but converting a JPEG to PNG does not recover quality lost during the original JPEG compression. The PNG will simply be a lossless copy of the already-compressed JPEG — and significantly larger.
