Format comparisons
Clear, side-by-side comparisons to help you pick the right image and audio format.
- WebP vs AVIF: which image format should you use? WebP and AVIF are both modern image formats built to load faster than JPEG and PNG. AVIF usually wins on file size and quality, while WebP wins on compatibility and encoding speed. Here is how they compare in practice.
- PNG vs JPG: when to use each image format PNG and JPG solve different problems. PNG is lossless and supports transparency, ideal for graphics and screenshots. JPG uses lossy compression that makes photographs much smaller. Picking the right one keeps images sharp and light.
- JPG vs WebP: should you switch your photos to WebP? JPG is the classic photo format that opens everywhere. WebP is a newer format that produces noticeably smaller files at similar quality. For websites, the switch can cut page weight significantly.
- MP3 vs WAV: compressed or lossless audio? MP3 and WAV represent two ends of the audio spectrum. WAV stores uncompressed, lossless sound; MP3 compresses it into a much smaller file. The right choice depends on whether you are editing or sharing.
- PNG vs WebP: which format is better for the web? PNG keeps every pixel losslessly and supports transparency, but files are heavy. WebP delivers similar quality at a fraction of the size and is supported by all modern browsers.
- AVIF vs JPG: modern compression or classic photos? JPG is the default photo format everywhere. AVIF uses the AV1 codec to shrink images further while keeping excellent quality, but support is newer.
- GIF vs WebP: animated images on the web GIF is the classic animated format with a 256-color limit. WebP supports animation with full color and usually produces much smaller files.
- HEIC vs JPG: iPhone photos and compatibility HEIC (HEIF) is Apple's efficient default for iPhone photos. JPG opens on virtually every device, which is why sharing often requires conversion.
- PDF vs JPG: documents or page images? PDF preserves layout, text and multiple pages in one file. JPG turns each page into a flat photo-style image that is easy to embed but not selectable text.
- BMP vs PNG: uncompressed bitmap or lossless PNG? BMP stores raw pixels with little or no compression, so files balloon. PNG compresses losslessly and supports transparency while staying sharp.
- WebP vs PNG: modern web or lossless master? Both support transparency. PNG is the lossless reference format every editor opens. WebP typically produces smaller files for the same visual result on the web.
- MP4 vs WebM: video for web and sharing MP4 (H.264) plays everywhere including phones and editors. WebM (VP9/AV1) is tuned for the web and can be smaller at similar quality in supported browsers.
- SVG vs PNG: vector source or raster export? SVG stores shapes as math—infinitely scalable for logos and icons. PNG rasterizes to fixed pixels, which every app opens but cannot scale up cleanly. Converting SVG to PNG is the bridge when a platform rejects vectors.
- JXL vs WebP: next-gen compression or safe web default? WebP is the proven modern web format with excellent browser support. JXL (JPEG XL) pushes compression further and can losslessly recompress JPEGs, but playback support is still catching up.
- FLAC vs MP3: archival quality or easy sharing? FLAC keeps every sample losslessly—perfect for archives and audiophile listening. MP3 throws away data for tiny files that play on any phone or car stereo.
- JPG 与 AVIF：经典照片还是新一代压缩？ JPG 无处不在。AVIF 用 AV1 在保持画质的同时进一步缩小文件。
- PNG 与 AVIF：无损母版还是轻量网页资源？ PNG 保留每个像素和透明度。AVIF 可用现代压缩在更小文件中达到相近视觉效果。
- HEIC 与 PNG：iPhone 存储还是无损分享？ HEIC 是 Apple 的高效默认格式。PNG 无损且各处可编辑 — 适合作为 iPhone 照片母版。
- M4A 与 MP3：Apple AAC 还是通用 MP3？ M4A 通常存 AAC — 常见于 iTunes 与播客。MP3 几乎可在任何设备和上传表单播放。
- OGG 与 MP3：开放 Vorbis 还是经典 MP3？ OGG（Vorbis）是开放格式，常见于游戏。MP3 仍是分享阻力最小的选择。
- WAV 与 FLAC：未压缩 PCM 还是无损压缩？ 两者均无损。WAV 存原始 PCM；FLAC 压缩且不丢失任何采样。
- PDF 与 PNG：多页文档还是清晰单页图？ PDF 将文字与多页合一。PNG 将单页导出为无损栅格 — 适合缩略图与幻灯片。
- GIF 与 PNG：调色板动画还是全彩静态图 GIF 可动画但限 256 色。PNG 无损全彩，适合透明 UI。
