JPG, PNG, WebP, GIF, SVG, or AVIF — which should you choose? The complete decision guide for web, print, social media, and design.
Photos on websites → WebP (or JPG as fallback)
Logos & icons on websites → SVG (or WebP/PNG)
Screenshots & UI graphics → PNG
Social media photos → JPG
Animations → WebP animated (or GIF for compatibility)
Print → TIFF or JPG at 95+ quality, 300 DPI
Next-gen web → AVIF (smaller than WebP, growing support)
The workhorse of the web for three decades. JPG uses lossy compression that works brilliantly on photographs — complex gradients and natural color variation compress efficiently with minimal visible quality loss at 80–85% quality settings. JPG does not support transparency and degrades slightly with each re-save, making it unsuitable as a working file format. Keep master copies in PNG or RAW and export to JPG only as a final delivery step.
PNG stores every pixel exactly as-is using lossless compression. This makes it perfect for graphics, logos, screenshots, and any image with text or sharp edges. Full 8-bit alpha transparency allows pixels to be any level of opacity, enabling graphics to sit over any background color. The trade-off is larger file sizes — PNG is 3–5x larger than equivalent JPG for photographic content. Never use PNG for photos on a public-facing website if performance matters.
Google's 2010 format designed to replace both JPG and PNG on the web. WebP achieves roughly 30% smaller files than JPG at equivalent quality in lossy mode, and 26% smaller than PNG in lossless mode. It supports full transparency, animation, and both lossy and lossless compression in one format. As of 2026, all major browsers support WebP. The only remaining limitation is software compatibility — not all desktop image editors handle WebP natively, though support has expanded significantly.
SVG is fundamentally different from the others — it stores shapes, paths, and text as mathematical descriptions rather than pixels. This means SVG scales to any size (phone screen to billboard) with zero quality loss. SVG files are often tiny for simple graphics, can be styled with CSS, and can be animated. SVG is the unambiguous best choice for logos, icons, and illustrations — use it whenever your source artwork is vector-based. It doesn't work for photographs.
GIF is an ancient format (1987) limited to 256 colors per frame, making it unsuitable for photographs. Its main surviving use case is simple animations — short looping clips and memes — where its universal compatibility still gives it an edge. For any new project, animated WebP or short video clips (MP4) produce much better results at smaller file sizes. Use GIF only when maximum compatibility with very old systems or platforms is required.
AVIF is the newest widely-supported format (based on the AV1 video codec). It achieves 50% smaller files than JPG and 20% smaller than WebP at equivalent quality — the most efficient common image format available. Browser support reached ~93% globally as of 2026. The main limitation is slower encoding time compared to WebP and JPG, and patchy support in design software. AVIF is the future of web images and worth adopting today for performance-critical applications.
| Use Case | Best Format | Reason |
|---|---|---|
| Website hero/background photo | WebP | Smallest size, great quality, universal browser support |
| Website logo | SVG | Scales perfectly, usually tiny file, CSS-styleable |
| Website icon | SVG or WebP | SVG for vectors; WebP for raster icons needing transparency |
| Screenshot with text | PNG | Lossless preserves sharp text; JPG/WebP lossy blurs it |
| Social media photo | JPG | Platforms re-compress anyway; JPG avoids double compression |
| Social media graphic/text | PNG | Stays crisp after platform re-compression |
| Animation / meme | Animated WebP | Better quality and smaller than GIF; use GIF only for compat |
| Print (brochure, poster) | TIFF or JPG 95+ | Maximum quality at 300 DPI; WebP not print-ready |
| Email newsletter photo | JPG | Small file loads fast; email clients vary in WebP support |
| App UI graphic | PNG or SVG | Transparency support; lossless quality |
| Design working file | PNG | Lossless, no generation loss, editable |
| Next-gen web performance | AVIF | 50% smaller than JPG; 93% browser support as of 2026 |
WebP is the best image format for websites in 2026. It produces smaller files than both JPG and PNG at equivalent quality, supports transparency, and is supported by all modern browsers. Use WebP for all web images, with JPG or PNG as fallbacks for very old browsers if needed.
JPG at quality 80–90 is the best format for social media photos. Most platforms re-compress uploaded images anyway, so using JPG reduces upload time and avoids double compression. For graphics with text or logos, PNG preserves clarity better when platforms re-compress.
For print, use TIFF or high-quality JPG (quality 95+) at 300 DPI or higher. PNG is also acceptable for print. WebP, GIF, and low-quality JPG are not suitable for print because they either don't support the color profiles printers use or have insufficient quality.
SVG is the best format for logos because it's vector-based and scales to any size without quality loss. When a raster format is required, use PNG for its transparency support and lossless quality. WebP is also an option for web-only logos.
For photographs, AVIF and WebP produce the smallest file sizes at equivalent quality — often 50–70% smaller than JPG. For lossless graphics, WebP lossless is about 26% smaller than PNG. For simple graphics with few colors, GIF can sometimes produce very small files.
