PNG to JPG Converter

How to Convert PNG to JPG Online

1. Upload Your PNG Files: Drag and drop your PNGs onto the page or click "+ Add Files" to pick them from your computer. Batch upload is supported — queue dozens of screenshots, photos, or exported designs in one pass.
2. Pick a Quality Preset: The default is "Very High (Recommended)" — visually indistinguishable from the source for photos. Drop to "High" or "Medium" if you need smaller files for web or email, or stay at "Highest" when the JPG will be reused in a print or editing pipeline.
3. Resize (Optional): Use the Image Resolution controls to keep the original dimensions, pick a Preset Resolution (720p, 1080p, 1440p, 2160p), scale by percentage, or type a custom Width x Height. Aspect ratio is locked unless you change both dimensions.
4. Convert and Download: Choose JPG or JPEG as the extension, click "Convert," and grab your files individually or as a ZIP. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.

Why Convert PNG to JPG?

PNG is a lossless raster format with full alpha transparency; JPG (JPEG) is an 8-bit lossy format with no alpha channel. For photographs that don't need transparency, JPG typically lands at one-fifth to one-tenth the size of the equivalent PNG — at high-quality settings, differences are imperceptible for photographic content, though JPG is a lossy format and the reduction is not lossless. That size delta is the entire reason this conversion exists.

• Shrink photo-style PNGs by 80-95%. A 5 MB iPhone screenshot of a wallpaper-style photo often drops to 300-500 KB as JPG at 90% quality — useful for Slack, Discord, and Gmail attachments.
• Stay under email and chat attachment caps. Gmail caps attachments at 25 MB and Outlook.com at 20 MB; Discord's free tier dropped to 10 MB in September 2024. Photographic PNGs routinely blow past those limits; JPG fits.
• Speed up websites. Google's Core Web Vitals penalize slow LCP. Swapping hero PNGs for JPG (or WebP) shaves hundreds of KB per image without changing layout.
• Match platform upload requirements. Some print-on-demand services, government portals, and older CMSs reject PNG or silently re-encode it to JPG anyway. Pre-converting gives you control over the quality setting.
• Reduce phone storage. Android screenshots default to PNG; Samsung and Pixel both let you switch, but converted JPGs save several GB across a typical screenshot folder.
• Send through MMS. US carriers still cap MMS at 0.6-3.5 MB depending on carrier and recipient — JPG is the only realistic photo format that fits.

PNG vs JPG — When to Use Which

Use PNG when sharp edges, text, UI elements, or transparency matter. Use JPG when the source is a photograph and file size matters more than pixel-perfect fidelity.

Quality Preset Guide

JPG quality below ~70% introduces visible blocking and color banding, especially in skies and skin tones. For anything user-facing, stay at 80% or higher.

Transparency Handling

JPG has no alpha channel, so every transparent pixel in your PNG has to be flattened against a solid color before encoding. This tool composites transparent areas against white by default — the standard behavior across virtually every PNG-to-JPG converter, including Photoshop's "Save As" and macOS Preview. If you need the original transparency to survive, convert to WebP instead — WebP supports alpha and typically beats both PNG and JPG on file size.

For logos and icons that will live on a non-white page, keep the PNG or convert to WebP. Once transparency is flattened to a JPG, it cannot be recovered.

Frequently Asked Questions

Does converting PNG to JPG reduce image quality?

Yes, slightly — JPG uses lossy DCT compression while PNG is lossless. At the default Very High preset (~90% quality), the difference is imperceptible to the human eye on photographic content. On graphics with sharp edges, text, or solid color regions, JPG compression introduces visible "mosquito noise" around edges; for that content, stick with PNG or convert to WebP, which handles both photos and graphics better.

Why did my transparent PNG become a JPG with a white background?

JPEG, defined in 1992 by the Joint Photographic Experts Group, supports only 8-bit RGB — no alpha channel. Any converter has to pick a solid color to replace transparent pixels; white is the de facto standard because it matches the default page background in most viewers, editors, and browsers. If the white halo bothers you, convert to WebP (which keeps transparency) or PNG to ICO for favicons.

What quality setting should I use?

Use Very High (90%) for general use — the savings vs Highest are large and the visual difference is essentially zero on photos. Drop to High (80%) for email attachments and blog content. Reserve Highest (~95%) for master copies that will be edited again, because every JPG re-save loses a small amount of detail. Avoid going below 70% unless file size is the only thing that matters.

Can I convert hundreds of PNGs at once?

Yes — drop a folder's worth of PNGs onto the upload area, set the quality preset once, and click Convert. The Conversion runs on our servers, so the only practical limit is upload size and connection speed. For very large batches (500+ files), do them in chunks of 50-100 to keep the browser responsive.

Will the JPG keep my PNG's resolution and aspect ratio?

By default yes — Image Resolution is set to "Keep Original." Switch to a Preset Resolution (720p, 1080p, 1440p, 2160p), enter a custom Width x Height, or scale by percentage if you want smaller dimensions. Aspect ratio locks when you change one dimension; type both values to break the lock.

My PNG is a screenshot — should I really convert it?

For screenshots of text, code, or UI, no — PNG's lossless compression preserves crisp pixel edges, and JPG will smear them. For screenshots of photos, videos, or game scenes, JPG is fine and much smaller. The mixed case (a photo screenshot with overlaid UI) is a judgment call: try High quality first, zoom to 200%, and see whether the UI text still reads cleanly.

How does JPG compare to WebP and HEIC for the same job?

WebP and HEIC both beat JPG on size at the same visual quality — typically 25-35% smaller. WebP is the modern web default; it's supported across Chrome, Firefox, Edge, Safari 16+ (partial since 14) and supports transparency, which JPG cannot. HEIC is the iPhone default but has weaker desktop support. Use PNG to WebP when you control the destination and want maximum savings; use PNG to JPG when you need the broadest possible compatibility.

Are my files private when I convert here?

Yes. Conversion happens on our servers — files are not stored long-term, never indexed, and never used for any other purpose. There's no watermark, no account requirement, and no email gating. Related conversions: JPG to PNG (the reverse), compress JPG (shrink existing JPGs), and PNG to PDF (bundle into a single document).
