Convert JPEG to PNG Format

Konvertering av JPG til PNG er viktig når du trenger tapsfri kvalitet eller gjennomsiktig bakgrunn. JPGs tapsbringende komprimering er utmerket for bilder, men skaper artefakter ved skarpe kanter. PNG bevarer hvert piksel nøyaktig og støtter full alfa-gjennomsiktighet.

Why Convert JPEG to PNG?

🖼️

Gjennomsiktige bakgrunner

PNG støtter full alfa-gjennomsiktighet. Fjern bakgrunner rent etter konvertering fra JPG.

✍️

Tekst og logoer

Skarpe kanter på tekst og former forblir artefaktfrie i PNG, i motsetning til uklare halos i JPG.

🔄

Ikke-destruktiv redigering

PNG mister aldri kvalitet ved lagring. Rediger og eksporter gjentatte ganger uten forringelse.

JPEG vs PNG: Complete Format Guide

Feature

JPEG

PNG

Compression

JPEGLossy

PNGLossless

Transparency

JPEGNot supported — transparent areas always render as solid white or the specified matte color

PNGFull 8-bit alpha channel — each pixel can be any opacity level from fully transparent (0) to fully opaque (255)

Animation

JPEGNot supported

PNGNot in standard PNG; APNG (Animated PNG) is a non-standard extension with limited, inconsistent support

Color Depth

JPEG24-bit (8 bits per channel: RGB) — up to 16.7 million colors

PNG24-bit RGB (16.7M colors) or 32-bit RGBA (16.7M colors + full alpha); up to 48-bit for professional workflows

File Size

JPEG50 KB – 5 MB per image depending on resolution and quality setting

PNG100 KB – 10 MB — significantly larger than JPG for photographic content

Browser Support

JPEGUniversal — all browsers, all operating systems, all devices including IE6 and older smartphones

PNGUniversal — all modern browsers, operating systems, and devices including IE7+

⚠️Converting JPG → PNG does NOT recover quality lost to JPG compression. It creates a lossless copy of whatever quality the JPG currently has — ideal for future editing, but existing compression artifacts cannot be reversed.

JPEG

About the JPEG

Standardized in 1992 by the Joint Photographic Experts Group, JPEG became the internet's dominant image format through the 1990s. Its DCT compression made digital photography practical for early web and digital cameras, enabling photo-sharing at a time when dial-up connections made large files impractical. Today it remains the default format for cameras, smartphones, and photo-sharing platforms worldwide.

Strengths

+Smallest file sizes for photographs (10:1 to 20:1 compression ratio)

+Universal compatibility across every device, software, and platform

+Embeds EXIF metadata (GPS, camera settings, date/time)

+Adjustable quality/size trade-off at save time

Limitations

−Lossy — permanently discards image data with every save

−No transparency — backgrounds are always solid

−Visible block artifacts on sharp edges, text, and high-contrast areas

−Quality degrades with each re-save (generational quality loss)

When to Use

→Sharing photographs on social media, email, or blogs

→Camera images where file size matters more than pixel perfection

→Web page photos where page load speed is the priority

→Any context requiring maximum cross-device and software compatibility

Tips

•Quality 85–95% delivers the optimal balance between file size and visual quality

•Never re-save a JPG after editing — use PNG or TIFF as your working master file

•Use PNG or WebP for logos, text, and graphics with sharp edges instead

•Strip EXIF metadata before web publishing to trim 5–20 KB per image

PNG

About the PNG

PNG was created in 1996 as a free, patent-unencumbered alternative to GIF after Unisys enforced its LZW compression patent. The PNG Development Group introduced full-color support, genuine alpha transparency, and superior lossless compression. It quickly became the web standard for logos, UI elements, and any image requiring a transparent background — a role it dominates to this day.

Strengths

+Lossless — every pixel preserved with zero compression artifacts

+Full 8-bit alpha channel for smooth, semi-transparent edges

+Ideal for text, logos, and graphics where sharpness is non-negotiable

+Unlimited re-saves without any quality degradation whatsoever

Limitations

−3–5× larger than JPG for photographic content

−No native animation support in standard PNG

−Slower to load than WebP for equivalent image content

−Not practical for very high-resolution photographs at web scale

When to Use

→Logos, icons, and brand marks placed over any background color

→Screenshots where text must remain perfectly sharp

→Images edited in multiple passes (keep as the master file)

→Web UI elements, buttons, icons, and interface assets

Tips

•PNG-8 (256 colors) halves the file size of PNG-24 for simple flat-color graphics

•Converting PNG to WebP typically saves ~30% file size with no visible quality change

•Alpha transparency requires PNG-24 or PNG-32 — PNG-8 only supports binary transparency

•Tools like pngquant can reduce PNG size by 50–80% with minimal quality impact
