Setup

How to Convert JPG to PNG Online

Three steps, fully local, no install.

Drop your JPGs

Drag JPG files (up to 100 at once). Anything your browser can read, JPG, JPEG, JFIF, is supported.

Export as PNG

PNG is lossless, every pixel of the JPG is preserved exactly. No quality slider needed.

Download PNG / ZIP

Single file downloads as .png, multiple files come zipped. PNG is typically 3-5× heavier than the source JPG (lossless compression).

Built for Editing, Layering and Print Workflows

When you need lossless quality and transparency support.

Lossless Output

PNG preserves every pixel. The conversion adds no compression artefacts on top of the JPG's existing ones, perfect for re-editing.

Bulk Conversion

Up to 100 JPG files in one batch. Drop a folder, all files queue automatically and download as a ZIP.

Editing-Ready

PNGs are the standard for re-editing in Photoshop, GIMP, Affinity. Layers, masks, transparency, JPG can't carry those, PNG can.

Total Privacy

Files never leave your browser. Verified locally via WebAssembly. Critical for confidential photos, screenshots, professional client work.

Instant Conversion

A 2 MB JPG converts to PNG in under 200 ms. Even 100 files complete in seconds, no upload waits, no server queue.

No Sign-Up, No Watermark

Free forever. The output is clean, ready for editing, layering, or any workflow that needs PNG specifically.

JPG vs PNG: When to Convert (and When Not To)

Picking the right format saves bytes and avoids quality loss.

When converting JPG to PNG makes sense

Re-editing: each save of a JPG re-compresses and adds artefacts. Convert to PNG once at the start of editing, work in PNG, export final to JPG. Need transparency: any output where parts must be transparent (logos on top of backgrounds, sprites, web graphics). Print at high resolution: PNG's lossless nature avoids any quality penalty in print. OCR or analysis: text detection and image analysis tools work better on PNG than JPG.

Re-editing, transparency, print, OCR, these need PNG.

When converting is pointless

Just for sharing: PNG of a photo is 3-5× heavier than the JPG without any visible quality benefit. Email, social media, web upload, keep JPG. Already-compressed JPG: converting to PNG won't restore lost detail. The PNG just preserves the JPG's existing artefacts at 3-5× the file size. Web hero images: WebP is a better choice if you need quality + small size + transparency.

Don't convert JPG to PNG just to convert. Have a reason.

PNG transparency: the bonus feature

JPG doesn't support transparency, PNG does. After conversion, you can use any image editor to make portions of the image transparent (subject extraction, background removal, watermarks). The original JPG's pixels stay intact; you're adding an alpha channel where you want it. For pure transparency on a logo, however, the source should be vector (SVG) where possible, converting JPG of a logo gives JPG-quality logo, not vector quality.

PNG enables transparency editing the JPG can't.

Privacy: why local matters

Most online JPG-to-PNG converters upload files to a server. For client photos, internal screenshots, or unreleased product images, that's a leak. Our tool processes inside your browser via WebAssembly. The file never leaves your device, no copies are kept, closing the tab erases everything from memory.

Local processing = your photo never leaves your device.

Format Comparison

Choose the right format for your use case

Aspect	JPG	When to use
Compression	Lossy	PNG = 3-5× larger	PNG for editing, JPG for sharing
Transparency	Not supported	PNG only	Logos, sprites, overlays
File size	Small (1-3 MB photo)	JPG wins on size	Email, web, social media
Re-editing	Each save adds artefacts	PNG for masters	Working files in editor
Compatibility	Universal	Both work everywhere	Either way

JPG to PNG, Frequently Asked Questions

Quick answers about the tool

How do I convert JPG to PNG online for free?

Drop your JPG files here, the tool converts them to PNG instantly in your browser, and downloads the result as a .png file (or a ZIP for bulk). No upload, no sign-up, no watermark. Bulk supports up to 100 files at once.

Will the PNG be larger than the JPG?

Yes, typically 3-5× larger. PNG is lossless: it preserves every pixel of the JPG without further compression. JPG was lossy, the PNG inherits all the JPG's pixel data faithfully but at PNG's larger storage size. This is normal and expected.

Does converting JPG to PNG improve quality?

No. Conversion can't restore information that was lost when the JPG was compressed. The PNG faithfully preserves what's in the JPG, including any compression artefacts. PNG is better for re-editing (no further loss across saves) and for transparency, not for restoring quality.

Can I make parts of the PNG transparent?

After conversion, yes, open the PNG in any image editor (Photoshop, GIMP, Photopea) and use the magic wand or selection tool to delete pixels, leaving them transparent. The conversion itself doesn't remove backgrounds, it just gives you a format that supports transparency.

Can I convert hundreds of JPGs 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, run multiple browser tabs in parallel, each tab keeps its own state and processes independently.

Is my JPG 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 from memory. Verify in DevTools → Network tab during conversion, zero outgoing requests with file payload.

Why convert JPG to PNG instead of WebP?

PNG has the widest compatibility for re-editing, every image editor reads PNG natively. WebP is lighter and supports transparency, but some editors (older Photoshop, some print workflows) still don't read it. Pick PNG for editing pipelines, WebP for modern web delivery.

Does conversion remove EXIF metadata?

PNG supports a different metadata format than JPG (tEXt chunks instead of EXIF). Most converters strip JPG's EXIF during conversion. To preserve specific metadata or strip it intentionally, use our EXIF Editor before or after conversion.
