Choose the right format

JPG is usually best for photos, forms, and smaller file sizes.

PNG is best for transparency, logos, stamps, signatures, and sharp graphics.

HEIC/WebP/AVIF are modern formats; convert them when older forms reject uploads.

Image Converter Tools for Upload Requirements

Many websites do not accept every image format. Some forms ask for JPG only, some design workflows need PNG, and iPhone photos often need HEIC conversion before upload. This image converter hub links the format-specific tools that solve those workflows.

If your converted file also needs a strict file-size limit, use the target-KB option inside the relevant converter or start from the main Photo Resizer in KB tool.

Tested as a converter tool collection

We check converter pages for supported formats, private browser processing, output downloads, target-KB behavior, sitemap inclusion, and internal links before publishing. Built and tested by Mozammel Hoshen Chowdhury. Review process: Editorial Policy.

Private by default

The converter tools are designed to run locally in your browser. That means personal photos, signatures, forms, and documents do not need to be uploaded to our server for normal conversion.
