PNG

Transparent Visuals

Lossless quality. Supports exact transparency channels. Excellent for brand logos and isolated graphics.

WEBP

Modern Web Standard

Next-gen compression format. Fully replaces PNG and JPG with 30%+ higher savings.

AVIF

High-Fidelity Codec

State-of-the-art compression offering clean color gamuts and pristine details.

Frequently Asked Questions

Is my privacy protected? Where are files converted?

Absolutely. All processing occurs securely via our high-speed endpoint and converted files are never stored or logged on persistent servers. Your original images never leave your control and are fully discarded.

Can I convert HEIC photos from iOS devices?

Yes! UtilVox implements instant client-side preprocessing that converts HEIC files seamlessly to JPEG/PNG before conversion, letting you handle standard mobile formats without additional apps.

What is the bulk processing upload limit?

To maintain server health and smooth browser rendering, you can convert up to 20 files in a single batch, up to 50MB per individual image.

Picking the Right Format, Not Just a Different One

The four formats that matter

Each format makes a different trade. Converting is about matching the format to the destination:

Format	Strength	Weakness
JPG	Small files for photos; opens everywhere	No transparency; quality loss on each re-save
PNG	Lossless; transparency; sharp text and lines	Big files for photographs
WebP	25–35% smaller than JPG at equal quality	A few older apps and portals reject it
HEIC	iPhone default; excellent compression	Poor support outside Apple devices

Conversions that help — and one that doesn't

PNG→JPG shrinks screenshots for email. JPG/PNG→WebP speeds up websites. HEIC→JPG fixes every compatibility problem iPhone photos have. The one that disappoints: JPG→PNG does not recover quality — compression artifacts are baked in, and you just get a bigger file with the same flaws. Convert to PNG only when you need transparency support or are about to edit text/line graphics.

Special cases

iPhone photos have a dedicated HEIC to JPG converter with batch support. If the goal is a smaller file in the same format, that's the image compressor's job, not conversion. Developers embedding images in CSS or JSON want image to Base64 instead.
