Convert PNG to JPG Under 1MB
PNG files are often several megabytes even for moderate-sized images, because PNG is lossless. Converting to JPG and compressing to under 1MB gives you a universally compatible file that loads fast on any device. For most photos at 1200–2000px, JPG at 85% quality lands well under 1MB automatically.

Step-by-Step Guide
5 steps · takes under 1 minute
Open the Convert to JPG tool
Go to the Convert to JPG tool — it converts PNG, WebP, GIF, and BMP to JPG in your browser.
Upload your PNG
Drop your .png file onto the upload zone. The tool reads it immediately with no server upload.
Set quality to 85%
At 85% quality, a 1200×800 PNG photo converts to a JPG of 120–200KB. A 2000px wide PNG converts to roughly 300–500KB — well under 1MB in both cases.
Check the output size
The tool shows the converted file size. If your PNG is extremely large (e.g. a 4K poster), try 80% quality or resize the image first using the Resize tool.
Download and confirm
Download the JPG. Verify file size is under 1MB. For a standard photo PNG, this process consistently produces files of 100–600KB depending on resolution and complexity.
100% Private — Zero Uploads
ImgToolkit runs entirely in your browser using the Canvas API. Your images are never sent to a server, never stored in the cloud, and never seen by anyone else. This makes it safe for sensitive documents, client work, medical imagery, and confidential screenshots.
Pro tip
Always keep your original file before converting. Lossy formats like JPG discard data permanently — you can't restore quality that was compressed away.
