Why This PNG Compressor Is Different
Exact KB targets
Compress PNG images to common limits like 50KB, 100KB, 200KB, 300KB, 500KB, or 1MB.
Batch and ZIP download
Compress up to 20 PNG images together and download all successful results in one ZIP.
Before and after preview
Check visual quality and output file size before saving the compressed PNG.
Optional dimensions
Set optional width or height limits when a target KB needs smaller dimensions.
Private local processing
Compression happens in your browser without uploading personal photos to a server.
Compress PNG to 100KB, 200KB, 500KB, or 1MB
Many forms, portals, email workflows, and profile uploads ask for a specific file-size limit. This tool focuses on target-KB compression instead of only giving a generic quality slider, so you can aim for the PNG size your upload form needs.
Reduce PNG File Size Online
Use this PNG size reducer when a website, form, CMS, or email attachment needs a smaller PNG file. Start with a preset like 50KB, 100KB, or 200KB, then adjust the target or optional dimensions if the PNG file size still needs to be lower.
Batch Compress PNG Files
Add several PNG photos when you need a full set compressed. You can preview each result, download one file, or save every successful compressed PNG as one ZIP.
Balance PNG Quality and File Size
PNG is a lossless format, so smaller targets often need smaller dimensions instead of lower image quality. The comparison preview helps you decide whether the compressed image still looks good enough before you download it.
Need Another Output Format?
Use Compress JPG for photos, Image to WebP for smaller web-ready files, or Photo Resizer in KB for mixed image formats and exact-KB resizing.
Private PNG Compression in Your Browser
PNG decoding, target-size compression, previews, and ZIP creation happen locally. Your images are not uploaded to our server during normal compression.
Tested for PNG compression
We test single and batch PNG compression, exact-KB targets, output dimensions, before-and-after previews, individual downloads, and ZIP creation. Built and tested by Mozammel Hoshen Chowdhury. Review process: Editorial Policy.
Frequently Asked Questions
How do I compress PNG to a specific KB size?
Upload one or more PNG images, choose a target such as 100KB, 200KB, 500KB, or 1MB, and click Compress. PNG is lossless, so the tool reduces dimensions when needed to reach smaller KB limits while keeping transparency where possible.
Can I batch compress PNG images?
Yes. Add up to 20 PNG images, compress them together, download each result, or download every compressed PNG in one ZIP file.
Can I compress PNG to 100KB or 200KB?
Yes. The preset buttons include common targets such as 50KB, 100KB, 150KB, 200KB, 300KB, 500KB, and 1MB. You can also type a custom KB value.
Can I reduce PNG file size without uploading?
Yes. This PNG size reducer runs in your browser, so decoding, resizing, compression, preview, and ZIP creation happen on your device.
Will PNG compression reduce quality?
PNG output is lossless at the final dimensions, but very small KB targets may require smaller pixel dimensions. The before-and-after preview helps you check the result before downloading.
Are my PNG files uploaded to a server?
No. PNG decoding, compression, preview, and ZIP creation run locally in your browser. Your images stay on your device.
Does this PNG compressor keep transparency?
Yes. The tool keeps transparent areas when the browser can decode and re-encode the PNG image correctly.
