PNG or JPG: which one to use?

PNG and JPG solve different problems. PNG uses lossless compression: it stores every pixel exactly as it was in the original and supports a transparent background. That makes it perfect for logos, icons, screenshots, and images with text — but it comes at the cost of file size.

JPG (or JPEG) takes the opposite path. It discards information the human eye barely notices to reach much smaller files. In photographs, the result is practically indistinguishable from the original at a fraction of the size. That’s why JPG remains the default format for cameras, emails, attachments, ad platforms, and enrollment systems.

Converting from PNG to JPG makes sense in three main situations: when the file is too heavy to send, when the site or form only accepts JPG, and when the image is a photo that doesn’t need transparency. Outside of those cases, consider keeping the PNG or switching to WebP instead.

How to convert PNG to JPG step by step

Start by adding your files. You can drag the PNG images directly into the dashed area at the top of the page, or click it to open your system’s file picker. There’s no limit on quantity: select a single PNG or dozens of them at once. On mobile, the picker opens your gallery and lets you select several photos in one go. As soon as the files come in, the tool starts processing immediately, with no confirmation button to click.

With a single file, the tool opens in Single image mode. You see the preview of the already-converted image and four indicators right below: original format, final format, original size, and final size. These numbers make it clear how much you saved before downloading anything. With two or more files, the tool automatically switches to Batch mode and shows a table with one row per image, listing the name, original size, converted size, and a status dot that turns green when that item’s conversion finishes.

The target format on this page is already set to JPEG, so there’s usually nothing to adjust. If you realize partway through that you need a different format, the buttons right above the preview let you switch to PNG, WebP, or BMP with no page reload or reselecting files — the conversion redoes itself instantly. You can also switch manually between single and batch mode using the two buttons at the top of the panel.

To finish, use the Download converted image button in single mode. In batch mode, the Download all converted (ZIP) button packs everything into one file. If you’d rather grab just a few, each table row has its own download button and an X to remove that image before generating the ZIP. All processing happens inside your browser: no image is ever sent to a server, which makes the tool safe for personal documents and private photos.

Frequently asked questions

Does converting PNG to JPG lose quality?

Yes, a little. JPEG uses lossy compression, so some detail is discarded to reduce file size. At the standard quality level, the difference is imperceptible to the naked eye in photos, but it becomes visible in images with fine text, straight lines, or flat color areas.

What happens to the PNG’s transparent background?

JPEG doesn’t support transparency. All transparent areas of the PNG are filled with white during conversion. If you need to keep the transparent background, convert to WebP instead of JPG — it supports an alpha channel and still produces smaller files.

How much smaller does the file get when converting PNG to JPG?

It depends on the content. In photos and screenshots with lots of colors, the reduction is usually between 60% and 90% — a 4 MB PNG becomes a 300 to 900 KB JPG. In logos, icons, and images with few flat colors, the gain is small or even negative, because PNG is already very efficient with that kind of image. The tool’s preview shows the final size before you download, so you can compare right away.

Can I convert several PNG files to JPG at once?

Yes. Drag as many files as you want into the upload area — the tool automatically switches to batch mode, converts all of them, and unlocks the ZIP download button. You can also download individual files from the table or remove ones you don’t want before generating the ZIP.

Why isn’t my 8 MB PNG accepted on the site I need to upload to?

Many application, enrollment, banking, and government forms cap uploads at 1 to 2 MB and only accept JPG. PNG stores the image losslessly, so a phone photo easily passes 5 MB in that format. Converting to JPG solves both problems at once: it drastically reduces the size and delivers the required format. If the file is still over the limit even as a JPG, also use the image compressor to fine-tune the final size.

Does converting PNG to JPG help my site’s PageSpeed?

It helps a lot when the images are photographic. Heavy PNGs are one of the most common causes of poor LCP (Largest Contentful Paint), one of the three Core Web Vitals metrics Google uses for ranking. Swapping PNG photos for JPG drops the page weight within minutes. It’s worth noting that PageSpeed Insights itself recommends going further and using WebP, which is on average 25% to 30% smaller than JPEG at the same quality.

Does the tool work on mobile?

Yes. It works in any modern browser — Android, iPhone, tablet, or computer — no app install needed. You can select photos straight from your phone’s gallery.
