Private conversion for the formats browsers use most
Format Fold is a single-image converter for PNG, JPG or JPEG, WebP, and AVIF. It reads the selected file locally, shows the source image and dimensions, then uses the browser canvas to create the requested output. A format may appear in the picker but still depend on the browser’s decoder and encoder support.
The converter accepts files up to 20 MB. It does not send the image to a conversion service, and the page’s Content Security Policy blocks background network connections from the converter. That makes it useful for private photos, design exports, screenshots, and other images you do not want to place on an upload-based website.
Format comparison
| Format | Often useful for | Important tradeoff |
|---|---|---|
| JPG | Photographs and broadly compatible opaque images | Lossy encoding can reduce file size, but may add artifacts; it cannot retain transparency. |
| PNG | Transparency, screenshots, logos, and crisp graphics | Lossless output can be larger, especially for photographs; it is not a quality-slider format in the same way as JPG. |
| WebP | Modern web images where smaller files and optional transparency are useful | Destination software or older workflows may not accept it, and quality changes can affect detail. |
| AVIF | Modern delivery where efficient compression is worth checking | Support varies more by browser and application; conversion can fail when decoding or encoding is unavailable. |
Preview, resize, and quality choices
The preview is the selected source image, not a claim that the browser has already rendered the final output. Width and height resize the canvas while preserving the current aspect ratio when you edit either dimension. The quality control matters mainly for JPG, WebP, and AVIF; PNG is lossless and browsers may ignore a quality value for it. Lower quality often produces a smaller lossy file, but the result depends on the image, dimensions, browser, and encoder.
Transparent pixels can remain transparent for formats that support alpha. JPG cannot carry transparency, so choose a white or black background when converting a transparent source to JPG. The same background controls can be useful when you need a predictable matte behind an image.
How it works
- Select one image. Choose a PNG, JPG/JPEG, WebP, or AVIF file under the 20 MB limit.
- Check the source preview. Format Fold displays the image and its dimensions in the browser.
- Choose an output. Select a format, adjust width or height, and set quality or background options that apply.
- Convert and download. The browser creates the file locally and starts the download without an upload step.
Browser compatibility and current limits
Image support is not identical across browsers. A browser may decode a format but not encode it, or it may reject a file that uses an unsupported codec profile. Format Fold reports an error when that happens; it does not route the image to a fallback server. The current tool handles one primary image at a time, does not promise metadata preservation, and does not guarantee that color profiles, animation, or every format-specific feature will survive a canvas conversion.
For a batch queue, saved presets, custom backgrounds, naming rules, and target-size web optimization, use the separately gated Format Fold Plus workspace. Those controls are not part of the basic single-image workflow described here.

Frequently asked questions
Does Format Fold upload images?
No. The selected image is decoded, previewed, and converted in the browser. The converter’s Content Security Policy blocks background network connections.
Which formats can I convert?
Format Fold accepts PNG, JPG or JPEG, WebP, and AVIF files. Output support depends on whether the current browser can encode the selected format.
What happens to transparent pixels when I choose JPG?
JPG is opaque and cannot preserve transparency. Choose a white or black background, or use PNG or a transparency-capable WebP output when the destination supports it.
Does the quality slider compress PNG files?
PNG is lossless, so browsers may ignore a quality value for it. Quality is more meaningful for JPG, WebP, and AVIF, where lowering it can reduce file size while also reducing detail.
Can Format Fold resize an image?
Yes. After loading one image, edit the width or height and Format Fold updates the other dimension to follow the source aspect ratio when you change either field.
Why might AVIF conversion fail?
AVIF decoding and canvas encoding vary by browser. Format Fold reports when the current browser cannot read the source or create the requested output; it does not upload the file to a fallback service.
