How to Convert PNG to JPG Online

Three-step workflow that runs entirely in your browser.

Drop your PNGs

Drag any number of PNG files (up to 100 at once). The tool reads them locally, no upload, no waiting.

Pick JPG quality

Default 92% is the sweet spot, visually identical to source for 99% of users. Lower for max compression, higher (95-100%) for archival.

Choose background colour

JPG doesn't support transparency. Pick a background colour (white default, but black or any hex works) for the area where your PNG was transparent.

Download JPG / ZIP

Single file downloads as .jpg. Multiple files come as a ZIP. Average size reduction: 70-85% vs the original PNG.

Built for Web Workflows and Email Limits

Convert PNG to JPG without sacrificing visible quality.

Bulk Conversion

Up to 100 PNG files in one batch. Drag a folder, all files queue automatically and download as a single ZIP.

Quality Slider

92% is the default sweet spot. Adjust between 60-100% to balance size vs detail. The preview shows the size estimate live.

Custom Background

Set the background colour for areas that were transparent in the source PNG. White, black, or any hex code. Matches your site's design system.

Total Privacy (Local)

Files never leave your browser. Verified locally via WebAssembly. Critical for confidential logos, documents, screenshots before launch.

Instant Conversion

A 4 MB PNG converts in under 200 ms. Even 100 files complete in seconds, no upload waits, no server queue.

No Sign-Up, No Watermark

Free forever. No account, no email, no upload limit. The output is clean, ready for your blog, e-commerce, email, or print.

PNG vs JPG: When to Convert

The compression and compatibility trade-offs that decide which format to use.

Why PNG is heavier than JPG

PNG is lossless: every pixel is preserved exactly. For a photograph with millions of unique colours, that means a 4-12 MB file for a typical phone-camera shot. JPG uses lossy compression, discards information the eye barely notices, typically producing files 5-10× smaller. For photos, the visual difference is invisible to almost everyone. Conversion to JPG is the right move whenever the image isn't a logo, screenshot, or diagram with sharp edges and flat colours.

PNG: lossless, heavy. JPG: lossy, light. Photos belong in JPG.

Transparency: the hidden gotcha

PNG supports an alpha channel (transparency); JPG doesn't. When you convert a PNG with a transparent area to JPG, the transparent pixels become whatever background colour you pick. For logos this often looks wrong, pick a brand-matched background, or convert to WebP instead (which keeps transparency at JPG-like compression). For photos with fully opaque content, transparency loss is irrelevant.

Transparent PNG → JPG = lose transparency. Always preview or pick a matching background.

Quality settings demystified

JPG quality is a number 1-100, but the relationship isn't linear. Above 95%: file size grows fast, quality gain invisible. 85-92%: the sweet spot used by Facebook, Instagram, Apple. 75-84%: visible artefacts on flat areas (sky, skin tones), but acceptable for thumbnails. Below 70%: blocking and banding visible. Stick to 92% as default; only drop lower for thumbnails or storage-critical use cases.

92% is the universal sweet spot. Drop only when bytes really matter.

Privacy: why local matters

Most online PNG-to-JPG converters upload your file to a server. For company logos, unreleased product mockups, screenshots of internal dashboards, or scanned documents, that's a leak. Our tool processes inside your browser via WebAssembly. Verify by opening DevTools → Network tab during conversion: zero outgoing requests with file payload.

Local processing = your PNG never leaves your device.

PNG to JPG, Frequently Asked Questions

Quick answers about the tool

How do I convert PNG to JPG online for free?

Drop your PNG files here, pick the JPG quality (92% is recommended), choose the background colour for transparent areas, and download. The whole process runs in your browser via WebAssembly, no upload, no sign-up, no watermark. Bulk supports up to 100 files in one batch.

Will I lose quality converting PNG to JPG?

Visually, almost never. JPG at 92% quality is indistinguishable from the source PNG to virtually all viewers. Technical loss happens (JPG is lossy by definition), but the eye doesn't notice for photographs. For logos with sharp edges or text, conversion can show subtle artefacts, keep PNG for those, or convert to WebP which preserves edges better.

What happens to the transparent background of my PNG?

JPG doesn't support transparency. The tool replaces transparent pixels with a background colour you pick (white by default). For logos, pick the colour that matches where the logo will be placed (e.g. site background). For photos with no transparency, this is irrelevant, the conversion is direct.

How much smaller will the JPG be?

Typically 70-85% smaller for photographs. A 4 MB PNG photo becomes 0.6-1.2 MB JPG. For graphics with flat colours (logos, screenshots) the savings are smaller, sometimes only 20-40%, because JPG isn't optimised for that content. Try the conversion to see the actual file-size delta for your image.

Can I convert hundreds of PNGs at once?

Yes, drop up to 100 files at a time, all queue automatically. The tool processes them in parallel where possible and bundles the output into a single ZIP. For thousands of files, run multiple browser tabs in parallel, each tab keeps its own state and processes independently.

Is my PNG uploaded to your server?

No. Conversion runs entirely in your browser via WebAssembly. The file never leaves your device, no copies are kept, closing the tab erases everything. Verify in DevTools → Network tab during conversion, zero outgoing requests with file payload.

Why convert PNG to JPG instead of WebP?

JPG has wider compatibility, every email client, social media, document editor, OS gallery viewer accepts it. WebP is lighter and supports transparency, but older software (pre-2020 versions of Photoshop, Office, Windows Photo Viewer) can't open it. Pick JPG for maximum compatibility, WebP for modern web performance.

Does it preserve metadata (EXIF, GPS)?

By default, basic EXIF data (camera model, capture date, GPS) is preserved during PNG-to-JPG conversion. To strip metadata before sharing (recommended for privacy), use our EXIF Editor on the resulting JPG to clean it.
