Skip to PNG to JPG converterLoading tool…
PNG stores pixels losslessly and supports transparency (alpha). JPEG uses lossy DCT compression—typically 60–85% smaller for photographs but cannot store transparent pixels.
This tool decodes your PNG locally, composites transparent areas onto a background color you choose, encodes JPEG at a quality level from 50–100%, and lets you compare the original PNG against the JPG output with a split slider before download.
Processing uses the HTML Canvas API (`drawImage` + `toBlob('image/jpeg', quality)`). No files are uploaded to EverydayTools servers—verify with your browser Network tab during conversion.
Pick an optimization profile (Website, Social, Email, etc.) or set JPEG quality (85 recommended for web photos) and a background fill for transparent areas.
Drag and drop, paste (Ctrl+V), or browse. Up to 20 PNG files, max 20 MB each. Conversion starts automatically.
Use the split slider to inspect transparency handling and artefacts. Select any file in the batch to preview it.
Download individual .jpg files or a ZIP that includes a conversion-report.json. Re-convert if you change quality or background.
Common real-world scenarios where this tool saves time.
Convert photographic PNG exports from design tools before publishing—pair with Image Resizer when dimensions exceed layout width.
Use the Email preset (Q75) to keep newsletters under provider attachment limits.
Use the Marketplace preset (Q88) for product photos that must stay sharp while meeting upload size caps.
Convert client or HR photos locally when cloud upload tools are not permitted—processing stays on-device.
Step-by-step chains that connect related tools for common tasks.
Input
hero.png (1920×1080, 3.1 MB, no transparency)Output
hero.jpg (~380 KB at Q85) — ~88% smallerReplacing a multi-megabyte PNG hero with JPEG is one of the fastest ways to improve LCP on content pages.
Input
logo.png (transparent, 240×80)Output
logo.jpg with black fill (#0f172a) at Q88Matching the fill color to the deployment background prevents a visible white box around anti-aliased edges.
PNG decode → alpha detection sample → background fill → drawImage → toBlob('image/jpeg', quality/100). Dimensions are preserved; alpha is replaced by the chosen solid color.
Choosing the right format for your asset type.
| Asset type | Best format | Reason |
|---|---|---|
| Photographs | JPG at Q85 | Lossy compression excels on smooth tones—large size savings |
| Logos with transparency | PNG or WebP | JPEG fills alpha with a solid color |
| Screenshots with text | PNG | JPEG blurs sharp edges |
| Email photos | JPG Q75 | Smaller attachments; use Email preset |
Quality settings available on this converter.
| Quality | Typical use | Notes |
|---|---|---|
| Q92–100 | Print, marketplace | Largest files; minimal artefacts |
| Q85 | Web default | Website profile—recommended starting point |
| Q82 | Social feeds | Social profile—platforms recompress uploads |
| Q75 | Email profile—attachment size limits | |
| Q50–70 | Thumbnails only | Visible artefacts on large displays |
| Related tool | Use this tool when | Use related tool when |
|---|---|---|
| Image Converter | You need PNG→JPEG with split preview, transparency fill control, and batch ZIP for photos. | You need WebP, AVIF, HEIC, or multiple output formats from one upload. |
| JPG to PNG | Shrinking photographic PNGs for web, email, or marketplaces without transparency needs. | You need lossless PNG for editing, screenshots, or transparency. |
| Image Compressor | Converting PNG to JPEG for the first time on photographic assets. | The file is already JPEG and you only need further size reduction. |
| WebP to JPG | Your source is PNG with alpha you must flatten to JPEG. | Your source is WebP (including animated WebP—first frame only there). |
A 4000 px-wide PNG at Q85 is still large—use Image Resizer to match display width first.
Raise to 90+ only when artefacts appear at 100% zoom; lower toward Q75 for email-only use.
Semi-transparent anti-alias pixels blend with the fill color—always check before publishing logos.
Transparent PNG logos pick up a white rectangle. Set background to your page hex (dark UI preset or custom color) and verify with the split preview.
JPEG blurs text edges. Keep UI captures as PNG or WebP unless a platform strictly requires JPEG.
JPEG conversion is irreversible. Archive the PNG if you may need transparency or lossless edits later.
Likely cause: Background fill does not match the page where the image is displayed.
Fix: Set fill to the exact deployment hex and re-convert. Use the checkerboard preview to inspect edges.
Likely cause: Flat-color graphics and screenshots compress efficiently as PNG already.
Fix: Skip conversion—PNG is the correct format. Try palette optimization or WebP via Image Converter instead.
Likely cause: Canvas memory limits on mobile or very high megapixel images.
Fix: Resize in Image Resizer first, then convert. Keep individual files under 20 MB.
Likely cause: Browser pop-up or download restrictions on mobile Safari.
Fix: Download JPG files individually from each card or use the mobile sticky Download button.
Keep PNG or export WebP with alpha via Image Converter. JPEG cannot preserve transparency.
Use Image Converter for format breadth. This page owns PNG→JPEG only.
JPEG is lossy. Retain the PNG original for future editing.
Use Compress Image to 200KB after conversion, or resize dimensions first.
Continue the workflow with the right follow-up tool.
No—this page is dedicated to PNG→JPEG with split preview, transparency fill, optimization profiles, batch ZIP, and impact stats. Image Converter handles many formats including WebP and HEIC.
Yes—JPEG is lossy. At Q85 most photo detail remains visually identical; text, flat graphics, and logos may show artefacts—keep those as PNG.
Q85 for web and social (Website profile). Q75 for email. Q88–92 for marketplace and print. Use the slider and split preview to inspect before download.
They are filled with your chosen solid color before JPEG encoding. Use the checkerboard split preview to verify edges—match dark sites with the Dark UI or custom hex fill.
Yes—up to 20 files per batch. Download individually or as a ZIP with a conversion-report.json listing sizes and settings.
No—conversion runs in your browser via Canvas. Open DevTools → Network during use; no image upload requests are sent to EverydayTools.
No—output JPG matches source width and height in pixels. Resize first with Image Resizer if you need smaller dimensions.
PNG is already efficient for flat graphics and screenshots. JPEG targets photographic content—try WebP via Image Converter for better compression on mixed content.
It overlays your original PNG (on a transparency checkerboard) against the JPG output so you can verify fill color and quality before downloading.
An illustrative milliseconds-saved figure based on byte reduction if the image were an LCP candidate—it is not a guaranteed Core Web Vitals score.
Images are processed locally with the Canvas API. No file bytes are transmitted to EverydayTools servers during conversion.
Output dimensions match the source. Quality and background settings are applied as selected. Alpha is replaced by the fill color—JPEG cannot store transparency.
Pipeline: PNG decode → alpha sample → fillRect(background) → drawImage → toBlob('image/jpeg', quality).
Confirm privacy by monitoring the Network tab—no upload POST/PUT requests during conversion.
Limitations: Animated PNG exports first frame only. CMYK PNGs may shift colors. Maximum 20 MB per file, 20 files per batch. Quality range 50–100%.
For publishing workflows—not a substitute for professional color-managed print pipelines.
