Image Formats Compared: JPEG, PNG, WebP ಮತ್ತು AVIF
Four formats cover more than 99% of images on the modern web. They make very different trade-offs between compression, transparency, animation and browser support. Here is a practical guide to choose the right one.
side-by-side comparison
Quick overview first, full breakdown of each format below.
| Property | JPEG ? | PNG ? | WebP ? | AVIF ? |
|---|---|---|---|---|
| compression | Lossy | Lossless | Lossy + lossless | Lossy + lossless |
| alpha (transparency) | APNG only | ಹೌದು (8-bit) | ಹೌದು (8-bit) | ಹೌದು (full) |
| animation | APNG only | Hanya APNG | Ya | Ya |
| max bit depth | 8-bit | 16-bit | 8-bit | 10/12-bit |
| typical size vs JPEG (photos) | 10/12-bit | 300–1000% | 300–1000% | 40–60% |
| browser support | universal | universal | universal | Chrome 32, Firefox 65, Safari 14 |
| typical encode speed | Chrome 85, Firefox 93, Safari 16 | Chrome 85, Firefox 93, Safari 16 | Seऔरg | Lambat |
JPEG — universal baseline
ಹೇಗೆ ಕೆಲಸ ಮಾಡುತ್ತದೆ
JPEG (Joint Photographic Experts Group) distandarkan 1992 ಮತ್ತು tertua di empat format ini. Memakai DCT lossy pada blok 8×8, kuantisasi, ಮತ್ತು entropi. quality dikendalikan angka 1–100. Encoder modern seperti MozJPEG mengejar 10–20% ukuran tanpa ubah aliran bit — setiap decoder JPEG bisa membaca.
ಗಾಗಿ best
Photographic content with smooth tonal gradients and plenty of detail — portraits, landscapes, product photography, hero images.
Kelebihan
- दुनिया ದ लगभग हर image viewer ನಲ್ಲಿ supported।
- लगभग हर जगह hardware-accelerated decoding।
- optimizers (MozJPEG, jpegli) ದ mature ecosystem।
Kekurangan
- alpha channel ಇಲ್ಲ — backgrounds flatten करने होंगे।
- text, line art ಮತ್ತು ವೇಗ edges ನಲ್ಲಿ blocky artifacts।
- सिर्फ़ प्रति channel 8 bits।
PNG — lossless ಮತ್ತು transparent
ಹೇಗೆ ಕೆಲಸ ಮಾಡುತ್ತದೆ
PNG (Portable Network Graphics) muncul pertengahan 1990an menggantikan GIF bebas paten. Benar-benar lossless: DEFLATE di atas filter per baris. Optimizer seperti oxipng (Rust, dari optipng) mencoba kombinasi filter/kompresi agar paling kecil tanpa ubah satu piksel.
ಗಾಗಿ best
UI graphics, icons, screenshots, diagrams, line art, logos with flat colors, and anything that needs a true alpha channel.
Kelebihan
- lossless — pixels round trip ನಲ್ಲಿ ಸುರಕ್ಷಿತ रहते हैं।
- full 8-bit alpha, प्रति channel 16 bits ವರೆಗೆ।
- universally supported।
Kekurangan
- photographs ನಲ್ಲಿ बड़ा — ಆಗಾಗ JPEG/WebP/AVIF ನಿಂದ कई गुना बड़ा।
- original spec ನಲ್ಲಿ animation ಇಲ್ಲ (APNG बाद ದ extension)।
WebP — Google ದ web-first format
ಹೇಗೆ ಕೆಲಸ ಮಾಡುತ್ತದೆ
WebP was released by Google in 2010, based on the VP8 video codec and later extended with a separate lossless mode. It supports both lossy and lossless compression in a single container, with optional alpha and animation. In lossy mode it typically beats JPEG by 25–35% at matching quality. In lossless mode it beats PNG by 20–30%.
ಗಾಗಿ best
General-purpose web delivery when AVIF is not yet safe — photos, UI sprites with transparency, animated GIF replacements, and as a fallback tier below AVIF.
Kelebihan
- एक format photos, graphics, alpha ಮತ್ತು animation cover करता है।
- comparable quality ನಲ್ಲಿ JPEG ಮತ್ತು PNG ನಿಂದ ದफ़ी छोटा।
- broad support: 2020 ನಿಂದ ಎಲ್ಲಾ evergreen browsers।
Kekurangan
- प्रति channel 8 bits — HDR ಇಲ್ಲ।
- कुछ low-end devices ನಲ್ಲಿ JPEG ನಿಂದ decode ನಿಧಾನ।
AVIF — compression ನಲ್ಲಿ current leader
ಹೇಗೆ ಕೆಲಸ ಮಾಡುತ್ತದೆ
AVIF (AV1 Image File Format) profil still-image codec video AV1, 2019, Alliance for Open Media. Warna hingga
12-bit, alpha, HDR, gamut lebar, sintesis film grain. Encoder referensi
(aom-av1 lewat libavif) lambat memberi kompresi terbaik untuk foto nyata.
ಗಾಗಿ best
Hero, galeri, ಮತ್ತು setiap saat bandwidth lebih penting dari waktu CPU. Baik sebagai tier atas elemen
<picture>.
Kelebihan
- best-in-class compression — ಸಾಮಾನ್ಯವಾಗಿ JPEG ನಿಂದ 40–60% छोटा।
- alpha, animation, HDR, wide gamut ಮತ್ತು 10/12-bit depth support करता है।
- royalty-free ಮತ್ತು open।
Kekurangan
- encode ನಿಧಾನ — build-time या async encoding ದ योजना बनाएँ।
- Safari ने support version 16 (2022) ನಲ್ಲಿ जोड़ा।
- synthetic graphics ಗಾಗಿ WebP lossless या PNG ನಿಂದ कम सुंदर।
कौन सा format ಬಳಕೆ करूँ?
- Foto, hero full-bleed: AVIF utama, WebP ಮತ್ತು JPEG caऔरgan lewat
<picture>. - Grafik UI transparan (ikon, logo): PNG kompatibilitas lama, WebP lossless ukuran kecil.
- Line art, tangkapan layar, diagram: PNG (atau WebP lossless) — JPEG/AVIF tidak ramah pada tepi tajam.
- Menggantikan GIF animasi: WebP atau AVIF — jauh lebih kecil, alpha asli.
- Satu format untuk semua peramban hari ini: JPEG untuk foto, PNG untuk grafis — bukan paling kecil, tanpa utang kompatibilitas.
Praktisnya tidak perlu pilih satu. Sajikan AVIF dulu, WebP kedua, JPEG atau PNG terakhir di
<picture> — setiap peramban dapat versi terkecil yang bisa didekode.
ಆಗಾಗ ಕೇಳಲಾಗುವ ಪ್ರಶ್ನೆಗಳು
JPG ಗೆ WebP ನಲ್ಲಿ ಹೇಗೆ convert करूँ?
Buka PicBrewery, letakkan JPG — WebP terbuat otomatis bersama JPEG, PNG, AVIF. Pilih sel WebP ಮತ್ತು klik unduh. Semuanya di peramban, tidak upload.
PNG ಗೆ AVIF ನಲ್ಲಿ ಹೇಗೆ convert करूँ?
PNG upload area ನಲ್ಲಿ drop ಮಾಡಿ ke PicBrewery. Enkode ke JPEG, WebP, ಮತ್ತು AVIF paralel di Web Worker. Klik kolom AVIF atau pilih banyak baris lalu unduh ZIP varian terkecil per sumber.
ಏನು AVIF WebP ನಿಂದ बेहतर है?
For photographs AVIF usually produces 20–30% smaller files than WebP at the same perceived quality, thanks to the AV1 video codec it is based on. WebP still wins on encoding speed and has broader browser support on older devices, so the two are complementary rather than one replacing the other.
ಏನು Safari WebP support करता है?
Yes. Safari has supported WebP since version 14 (macOS Big Sur, iOS 14, released in 2020). All current Safari versions decode both lossy and lossless WebP.
ಏನು PNG ನಾವುेशा lossless है?
Yes. PNG uses DEFLATE compression, which is strictly lossless: pixels decoded from a PNG are bit-identical to the source. Size reductions come from better filter choices and DEFLATE tuning (tools like oxipng), never from discarding image data.
ಏನು JPEG ನಲ್ಲಿ transparency हो सकती है?
No. Classic JPEG has no alpha channel. If you need transparency you must use PNG, WebP or AVIF. JPEG XL adds alpha but is not yet broadly supported in browsers.
JPEG ನಿಂದ AVIF कितना छोटा है?
Typical photographs encoded with a modern AVIF encoder (aom / libavif) are 40–60% smaller than MozJPEG output at equivalent perceptual quality. The savings shrink on low-detail graphics and flat colors, where JPEG already compresses well.
ಏನು मेरा browser AVIF decode करेगा?
Chrome 85+, Firefox 93+, Edge 121+, Safari 16+. Pakai <picture> dengan caऔरgan WebP/JPEG.
ಏನು PicBrewery वास्तव ನಲ್ಲಿ client-side है?
Yes. Decoding and re-encoding happen in WebAssembly inside Web Workers on your own device. No image bytes are sent over the network — the only requests are to load the static application and codec files.
