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 vs AVIF: classic photos or next-gen compression? JPG is the default everywhere—email, print, legacy CMS uploads. AVIF shrinks photos further with the AV1 codec while keeping excellent detail, but support is newer. Pick based on where the image will live.
- PNG vs AVIF: lossless master or tiny web asset? PNG preserves every pixel and supports transparency—ideal for UI and screenshots. AVIF can deliver similar visual quality at a fraction of the size using modern compression.
- HEIC vs PNG: iPhone storage or lossless sharing? HEIC is Apple's space-efficient default for photos. PNG is a lossless, widely editable format—great when you need a master file or transparency after editing an iPhone shot.
- M4A vs MP3: Apple AAC or universal MP3? M4A usually stores AAC audio—common on iTunes, podcasts and iPhone exports. MP3 plays on virtually every device, car stereo and upload form.
- OGG vs MP3: open Vorbis or classic MP3? OGG (Vorbis) is an open format common in games and Linux pipelines. MP3 remains the lowest-friction choice for sharing because every player understands it.
- WAV vs FLAC: uncompressed PCM or lossless compression? Both are lossless. WAV stores raw PCM—simple but huge. FLAC compresses without losing a single sample, often halving storage versus WAV.
- PDF vs PNG: multi-page document or sharp page image? PDF keeps text, vectors and multiple pages together. PNG exports a single page as a lossless raster—perfect for thumbnails, slides or further image editing.
- GIF vs PNG: animation and palette vs true-color stills GIF supports animation but limits colors to 256. PNG is lossless, full-color and ideal for crisp still graphics and UI with transparency.
