Frequently Asked Questions
Popular conversions: HEIC to JPG converter, PNG to WebP converter, JPG to AVIF converter, PDF to PNG converter, TIFF to JPG converter.
To convert HEIC to JPG online, drop your HEIC photos into QuickImager, choose JPG as the output, and download the results. Everything runs locally in your browser, so your files stay private with no uploads.
PNG vs WebP comes down to quality and file size: PNG is lossless and great for logos, screenshots, and transparency, while WebP usually produces smaller files for the web. If you are optimizing page speed, try converting PNG to WebP and compare the results.
AVIF vs WebP is a trade-off: AVIF can deliver smaller files at similar quality, but it is newer and not supported everywhere. WebP generally has broader support across modern browsers and is a solid default for web images.
By default, QuickImager removes metadata (including EXIF) to protect your privacy. If you disable “Remove metadata”, we will try to preserve compatible metadata when the source and output formats support it.
Batch conversion limits are up to 20 files at a time. Each file can be up to 50MB (and up to 100MP), and very large batches may take longer depending on your device.
QuickImager lets you convert to JPG, PNG, WebP, AVIF, GIF, TIFF, BMP, and ICO. You can also use HEIC, PDF, and SVG as input formats, but those are exported to a supported image output format.
Conversion is private: your files are processed on your device and are not uploaded to a server. QuickImager can work offline after the page (and any required format libraries) have loaded once.
