How to use the
Image Converter
- 01
Choose your source images
Select, drop or paste images with no fixed file-count cap. Actual file bytes are checked; a misleading extension does not turn another document into an image.
- 02
Choose format and quality
Use PNG for transparent artwork, JPEG for compatible photographs, or WebP/AVIF when the destination supports them. Select a background fill before exporting JPEG.
- 03
Inspect and download
Compare dimensions and file sizes. Download individual results or create a ZIP; errors for one batch item do not erase successful files.
What each output preserves
| Format | Useful for | Tradeoff |
|---|---|---|
| PNG | Transparent artwork and lossless pixels | Can be larger than photographic formats. |
| JPEG | Photos and broad compatibility | Lossy, without transparency. |
| WebP / AVIF | Compact web images | Destination support varies; AVIF encoding takes longer. |
| GIF | Simple still graphics | 256-color palette; animated sources become a still frame. |
| BMP / ICO | Legacy bitmaps and icons | BMP fills transparency; ICO includes 16, 32, 48 and 256px frames. |

Metadata is not copied into the new image.Input formats and deliberate boundaries
TIFF uses its first page, and animated GIF uses its first frame. SVG must be self-contained: embedded images, scripts, external references and CSS URLs are rejected. HEIC/HEIF requires native browser decoding; the common copyleft WASM decoder is excluded by this project’s permissive-license requirement.
Every file is limited to 40 MB and 24 megapixels. There is no fixed file-count or combined upload-size cap; practical queue size depends on device memory. Decoding is isolated from the page, but your device still needs working memory for uncompressed pixels. Cancel terminates the processing worker.
Image Converter:
questions, answered.
Does conversion preserve EXIF metadata?
No. Images are decoded into pixels and encoded again. Camera, location and original metadata are not copied.
Will animated GIF remain animated?
No. This converter exports a still image from the first frame. Use an animation-specific tool for multiple frames.
Why does HEIC fail in my browser?
HEIC depends on the browser’s native decoder. Export JPEG or PNG from your photo application if it is unavailable.
Can a converted image be bigger?
Yes. Format, image detail, transparency and quality all affect the output size. The actual before/after sizes are shown.
The calculations and checks above describe this tool's implementation. Use these primary references for the underlying formats and publishing guidance.
