PNG to JPG: what changes and when it makes sense

PNG is a Portable Network Graphics format. It is best known for exact pixel reproduction, crisp text and edges, and full alpha transparency. The main drawbacks are large files for photographs and no lossy mode for trading quality against size.

JPG is a Joint Photographic Experts Group format. It is best known for small files for photographs and near-universal compatibility. The main drawbacks are no transparency, visible blocking at low quality, and quality that drops every re-save.

PNG vs JPG at a glance

Property	PNG	JPG
Type	Raster image	Raster image
Compression	Lossless (DEFLATE), with an optional 8-bit palette mode	Lossy (DCT based, with chroma subsampling)
Transparency	Full alpha channel with soft edges	None
Animation	No	No
Colour depth	8 or 16 bits per channel, or 8-bit indexed colour	8 bits per channel (24-bit colour)
Support	Opens in every browser and image editor	Opens in every browser, operating system, camera, editor and print service
History	Created in 1995 as a free, patent-unencumbered replacement for GIF after Unisys began charging royalties for LZW compression. Became a W3C Recommendation in 2003. The signature bytes are 89 50 4E 47 0D 0A 1A 0A — "PNG" with newlines designed to catch file corruption.	Created in 1992 by the Joint Photographic Experts Group and standardised as ISO/IEC 10918. It became the default image format of the early web because it offered photographic compression when storage was expensive. Still the most widely used photo format 30+ years later.

What actually changes in this conversion

Moving from a lossless format to JPG is where you trade fidelity for size. Start high and lower until the difference becomes visible.
JPG cannot store transparency, so transparent areas are filled with white.
Expect the JPG file to be far smaller than the PNG source.
EXIF, GPS and camera data are stripped on every conversion. That is good for privacy, but you lose capture dates.

About PNG: history and technical details

Created in 1995 as a free, patent-unencumbered replacement for GIF after Unisys began charging royalties for LZW compression. Became a W3C Recommendation in 2003. The signature bytes are 89 50 4E 47 0D 0A 1A 0A — "PNG" with newlines designed to catch file corruption.

Technical: Uses DEFLATE (LZ77 + Huffman) compression. Two main modes: 8/16-bit truecolour with alpha, and 8-bit indexed with up to 256 colours. Filters per scanline (None, Sub, Up, Average, Paeth) before DEFLATE for better ratios.

Real-world size: A 1920x1080 screenshot is 200-600 KB as PNG. As JPG at quality 85 it is 100-300 KB but with blurry text. A 12-MP photo is 18-25 MB as PNG, 2-4 MB as JPG. PNG wins on text, JPG wins on photos.

Popular tools: Adobe Photoshop, GIMP, Figma, Sketch, Snipping Tool, macOS Screenshot, ImageMagick, pngquant, oxipng.

Alternatives: WebP lossless (20-30% smaller), AVIF (better for photos), JPG (photos only), SVG (vector graphics).

About JPG: what you get

Created in 1992 by the Joint Photographic Experts Group and standardised as ISO/IEC 10918. It became the default image format of the early web because it offered photographic compression when storage was expensive. Still the most widely used photo format 30+ years later.

Technical: 8x8 block Discrete Cosine Transform with 4:2:0 chroma subsampling by default. Baseline supports 8-bit per channel. Progressive loads in waves. Maximum dimensions 65,535 by 65,535 pixels. Maximum 16.7 million colours.

Real-world size: A 12-megapixel photo at quality 85 is typically 2-4 MB. The same photo as PNG is 18-25 MB, as BMP is 36 MB. JPG is 60-80% smaller than PNG for photographs.

Popular tools: Adobe Photoshop, GIMP, Affinity Photo, Lightroom, macOS Preview, Windows Photos, ImageMagick, FFmpeg.

Alternatives: WebP (25-35% smaller), AVIF (30-50% smaller), HEIC (50% smaller, Apple only), PNG (lossless, 5-10x larger).

Browser and software compatibility

PNG: Opens in every browser and image editor. JPG: Opens in every browser, operating system, camera, editor and print service.

JPG output opens in virtually every browser, operating system and editor.

Why people move away from PNG

A PNG of a photograph is commonly several times larger than the same image as JPG or WebP, which hurts page weight.
Screenshots and photos exported as PNG are among the heaviest assets on many sites.
Some upload forms and print services reject PNG or downscale it aggressively.

Why people choose JPG

JPG opens everywhere, from email clients to print kiosks to old CMS uploaders.
Photographs compress very well as JPG, so files stay small enough for email and upload limits.
Many portals, such as job applications and government forms, accept JPG only.

Common mistakes with PNG

Using PNG for photographs — files are 5-10x larger than JPG with no visible benefit
Saving screenshots as JPG by mistake — text becomes blurry and unreadable
Forgetting PNG transparency — white backgrounds appear where there should be alpha

Common PNG to JPG scenarios

Photos saved as PNG by mistake: Screenshots of photos and some design exports produce PNGs many times larger than needed.
Email and form limits: When an upload has a 2 MB cap, JPG usually fits where PNG does not.
Print and marketplace listings: Many print services and listing platforms prefer JPG.
Instagram and social: Instagram compresses images anyway; uploading JPG preserves quality better.

Best practices for keeping quality

PNG sources often contain transparency. Decide before converting what should replace it: white, black or a brand colour.
For web use, quality 80-85 is the sweet spot. Below 70, blockiness becomes visible in skies and gradients. For print or archiving, use 90-95.
JPG has no alpha channel. Transparent areas become a solid colour, so check the edges of cut-out subjects for halos.
Resize before converting if the image will be shown small. A 4000 pixel photo displayed at 800 pixels wastes bytes in any format.
Check the result at 100 percent zoom, especially around text, edges and gradients, before you replace any originals.
Keep your original files. Conversions to a lossy format cannot be undone.
When you convert a set of images, use the same quality setting for the whole batch. The converter handles up to 20 files at once.

PNG to JPG questions

Quick answers about privacy, quality, supported formats, file limits and how JPG works.

Why does my PNG to JPG conversion look blurry?

PNG has sharp edges and text. JPG compresses those with "ringing" artefacts. Use quality 90+ to minimise this. For text-heavy images, do not convert — use PNG or WebP lossless instead.

How much smaller is JPG than PNG?

For photographs, JPG at quality 85 is typically 60-80% smaller than PNG. For screenshots with text, JPG may actually be larger AND blurrier, so PNG or WebP is better.

Does JPG keep PNG transparency?

No. JPG has no alpha channel. Transparent areas become white in the output. If you need transparency, use WebP or PNG instead.

Why convert PNG to JPG?

JPG files are typically smaller than PNG, which makes them faster to share, send and load. The trade-off is a small amount of image detail at low quality settings.

Will converting PNG to JPG lose quality?

At 90% quality, most people cannot tell the difference. Use 85-95% for photos and you are fine.

Does JPG keep transparency?

No. JPG does not support transparency. Transparent areas will be filled with white.

Are my files uploaded?

Never. Everything runs in your browser. Your files never leave your device. Open DevTools Network tab while processing — you will see no upload request.

Can I convert many files at once?

Yes, up to 20 files at once. Download them individually or all together as a ZIP.

Does the converter strip metadata?

Yes. Browsers do not pass EXIF data through a canvas, so GPS, camera model and dates are removed on every conversion. That is good for privacy.

Is it free?

Yes. No credits, no daily cap, no account, no watermark. The practical limit is your device memory.

Is JPG always lossy?

Yes. JPG uses lossy DCT compression exclusively. There is no lossless JPG mode in normal use. Every save throws away some information, though at quality 90+ the loss is invisible to most people.

What does JPG stand for?

Joint Photographic Experts Group — the ISO committee that created the standard in 1992. The file extension is sometimes .jpeg, but both are identical.

Can JPG be animated?

No. JPG is a single-frame format. For animation use GIF, WebP, or MP4 video. Animated JPG variants exist but are not supported by browsers.

Your files never leave your device

No upload, no account, no tracking. Everything happens in your browser using the Canvas API and WebAssembly. You can confirm this in your browser's DevTools Network tab while the tool runs — no request carries your file. See why ToolDeck is different.
