TIFF to AVIF

An AVIF file is an image saved in the AV1 Image File Format — a modern, highly compressed format used across the web. It holds the same kind of photo or graphic a JPG would, but at roughly half the file size. The catch: it's new enough that some older apps and devices can't open it yet, which is usually why you landed here. If you just downloaded an image and it saved as something ending in .avif that won't open, you're in the right place. This guide explains what the file is, why you're suddenly seeing them, and exactly how to open one on Windows, Mac, iPhone, Android, and Linux — plus the one fix that works everywhere.

Image conversion online is the process of changing an image file from one format to another directly in your browser — no software to install, no account required. Transfonic supports 10 image formats, including JPG, PNG, WebP, HEIC, AVIF, GIF, BMP, TIFF, ICO, and SVG, converting between them in seconds for free.

This guide covers the full JPG vs JPEG story, when and why you might need to change between them, and how to convert your JPEG to other formats like WebP, BMP, TIFF, and SVG using Transfonic's free Image Conversion tool — no software, no signup required.

SVG files are the gold standard for logos, icons, and illustrations. They scale to any size without losing sharpness because they store shapes as mathematical paths rather than pixels. But most platforms — social media, email clients, Microsoft Office, Google Docs — do not support SVG uploads. When you need your vector graphic to work everywhere, PNG is the format that solves it. Converting SVG to PNG turns your infinitely scalable vector into a fixed-resolution raster image that opens on any device, uploads to any platform, and embeds into any document without compatibility issues. The challenge is doing it correctly — preserving transparency, choosing the right resolution, and avoiding the blurry output that comes from using the wrong tool or the wrong settings. This guide covers five methods, explains exactly how to handle transparency and DPI, and shows you how to choose the right SVG output format for your specific use case. For the fastest conversion with no setup, use Transfonic's SVG to PNG converter — free, browser-based, no account required.
