Image conversion without handing over the image

ConvertPics is a browser-based image format converter built for the awkward moment when a useful image will not open, upload, or fit the next workflow.

What the site does

The converter reads AVIF, HEIC, HEIF, JPG, PNG, and WebP files on your device. It can resize decoded pixels and export them as JPG, PNG, or WebP. Batch jobs run sequentially to reduce memory pressure, and multiple outputs can be collected in a ZIP archive.

The core conversion does not require an account. Files are not sent to a ConvertPics upload endpoint. They remain in browser memory until you remove them, refresh the page, or close the tab.

Why local processing matters

Photos can contain private documents, home interiors, family members, product prototypes, client work, and location metadata. A conversion task should not require a user to place those images on an unknown server when modern browsers can do the work locally.

Local processing also removes the upload and download wait. The tradeoff is that performance depends on the device. Large phone photos and long batches use more memory, particularly on older mobile browsers.

How our guidance is written

Format pages explain the practical differences that affect a real conversion: compatibility, transparency, lossy versus lossless encoding, file-size expectations, animation, and metadata. We avoid claiming that conversion restores lost detail or makes every file smaller.

Browser and codec support changes over time. We review the converter against current browsers and update guidance when a format or decoding path changes. If a file fails, the error stays visible so it can be reported rather than silently replaced with a lower-quality result.
