What makes Format Fold private?

The converter processes the selected image in the browser and ships with a Content Security Policy that blocks background network connections from the converter.

Can I convert any image format?

Format Fold is built for PNG, JPG or JPEG, WebP, and AVIF. A specific conversion still depends on the browser’s ability to decode the source and encode the requested output.

Does local processing preserve metadata?

No preservation guarantee is made for metadata, color profiles, animation, or other format-specific properties because the basic workflow uses a browser canvas.

Convert Images Privately in Your Browser

Format Fold is a private image converter for people who need a practical PNG, JPG, WebP, or AVIF conversion without uploading a personal photo or design file to a third-party service.

Local by design: the selected image is decoded, previewed, resized, and exported in the browser. The converter does not use an external conversion API.

What the private workflow supports

Format Fold handles one image at a time, accepts files up to 20 MB, and offers PNG, JPG, WebP, and AVIF input and output when the browser supports the required codec. You can inspect the source preview, change width or height, adjust quality for applicable formats, and choose a background when transparency needs to become opaque.

Choose a format by the job

JPG: a familiar choice for photographs and opaque destinations, with lossy quality tradeoffs.
PNG: useful for transparency and crisp graphics, with lossless-style output that may be larger.
WebP: a modern web option that can be smaller for some images and can support transparency.
AVIF: an efficient modern format when the browser and destination both support it.

How to use the private converter

Open the Format Fold converter and choose a supported local image.
Review the source preview and dimensions; no upload progress is involved.
Pick the output format, dimensions, quality, and background choices that fit the destination.
Convert and download the file, then validate it in the application where it will be used.

Privacy and browser limitations

A local workflow reduces the exposure created when an upload-based converter receives a private image. It is not a promise that every browser feature behaves identically: decoding, AVIF support, canvas encoding, color profiles, metadata, animation, and unusual source properties can vary. Format Fold reports unsupported format operations instead of routing your file to a remote fallback.

Private image conversion questions

Is my image transmitted anywhere?

The converter’s image workflow is local to the browser, and its Content Security Policy blocks background network connections. Format Fold does not call an external conversion API.

Can I use Format Fold for AVIF?

Yes when the current browser can decode AVIF and encode the requested output. Support is capability-dependent, so an AVIF file may fail in one browser and work in another.

Does private processing mean perfect preservation?

No. The browser canvas workflow does not promise preservation of metadata, color profiles, animation, or every source-format property. Check the result where you plan to use it.
