Frequently Asked Questions

PNG 文件通常比 JPG 大 5–10×。上传你的 PNG,选择画质级别,即可下载体积小得多的 JPG——非常适合邮件附件、网页以及有体积限制的上传表单。页面会显示前后体积对比,让你直观看到节省效果。

usage

JPG 不支持透明度,因此在转换过程中透明区域会被平展为纯色背景(默认为白色)。如果你需要保留透明度,请改为转换成 WebP,或之后使用抠图工具重新抠出主体。

technical

可以。切换到批量模式,添加你所有的 PNG,它们会被一起转换,并打包为单个 ZIP 供下载。批量转换是高级版功能;单张 PNG 转 JPG 始终免费且无水印。

features

The quality slider runs from 20 to 100 and defaults to 90, which is a safe balance of sharpness and file size. Drop it to around 75 for email attachments or web uploads where every extra KB counts, and keep it near 95-100 for print or archival copies where detail matters more than size.

quality

Yes. Since JPG has no alpha channel, a Background fill color field lets you pick any hex color to replace transparent pixels instead of the default white — useful if your PNG will sit on a colored web page or brand background. A Reset link puts it back to white in one click.

features

Set the background fill to match wherever the image will be displayed (white for most uses, or your page's exact background color), and keep quality at 90 or above so fine lines and text in the logo stay crisp instead of showing JPEG blur around edges.

tips

How PNG to JPG helps you get it done

Real problems it solves every day — for businesses, creators, and everyday tasks. Find the use case that fits you and start in seconds.

Productivity

Support Ticket & Docs Screenshot Shrinking

Convert bulky PNG screenshots from bug reports and how-to docs into small JPGs with the quality slider, so they fit ticket-system and email attachment limits without losing legibility.

Web & SEO

Faster-Loading Web Page Images

Turn PNG hero photos and banners into JPGs at 75-85% quality to cut page weight and improve load time and Core Web Vitals, since JPG is typically 5-10x smaller than PNG for photographic images.

Real Estate

Real Estate Listing Photo Uploads

Convert a folder of PNG property photos to JPG in Batch mode so every listing photo meets MLS and listing-site upload size limits in one pass, downloaded as a single ZIP.

For E-commerce

Marketplace Product Photo Batches

Etsy and Amazon sellers can batch-convert PNG product renders to JPG with a white or brand background fill, meeting marketplace format requirements for an entire catalog at once.

Photography

Photography Client Gallery & Print Lab Delivery

Photographers convert large edited PNG exports to JPG at 90-100% quality for client proofing galleries and print labs that require JPG uploads, keeping file sizes manageable with no visible loss of detail.
