PNG files behave differently from JPGs, and that difference matters when you need to hit a hard limit like 200 KB. This guide explains why PNGs shrink differently, when you should keep the PNG format, and how to get under any file-size budget quickly using the free browser compressor on this site.
Need it done now? Drop your PNG into the compressor, pick 200 KB (or any target), and download the result — all processing stays on your device.
Compress my PNGWhat makes PNG different from JPG
PNG is a lossless format: it stores every pixel exactly, using lossless DEFLATE compression. This gives it two signature strengths — perfect sharpness for screenshots, logos, text and line art, and full alpha transparency — and one big weakness: photographic content produces enormous files. A camera photo saved as PNG can easily be 5–10× larger than the same photo as JPG.
JPG, in contrast, is lossy: it discards visual information to save space, and it does not support transparency. That's why the right compression strategy depends on what's inside your PNG.
Decision guide: keep PNG, or convert?
| Your PNG contains… | Best approach |
|---|---|
| Screenshots, UI captures, text, line art | Keep PNG — lossless still matters; reduce dimensions and use a PNG optimizer |
| Logos / icons with transparency | Keep PNG or convert to WebP (also supports transparency, much smaller) |
| Photos without transparency | Convert to JPG or WebP — massive savings, no visible loss at sensible quality |
| Photos with transparency | Convert to WebP — the only modern format with transparency AND small photographic files |
Why a browser compressor can't shrink PNG below a floor
Because PNG is lossless, "quality" cannot simply be dialed down — every pixel must be preserved exactly. Practical levers for shrinking a PNG are:
- Reducing pixel dimensions — a 2000×1600 screenshot resized to 1000×800 has 75% fewer pixels and compresses far below half the original size.
- Reducing color depth — converting to a palette of 256 colors (PNG-8) can cut file size by 60–80% for graphics with flat colors.
- Converting to a lossy format — JPG or WebP when the content allows it.
The JpegDiet compressor handles this automatically: when your target is 200 KB and the output format is set to JPG or WebP, it binary-searches quality and, if needed, gradually scales dimensions until the file fits your budget. If you specifically need the output to remain a PNG, use the "Max dimensions" option to pre-shrink the image in an external PNG optimizer, then convert here.
Step-by-step: compress a PNG to 200KB
- Open the compressor on this site.
- Drag your PNG file (or files) into the drop zone.
- Set target size to 200 KB.
- Choose the output format:
- JPG — smallest for photos, but loses transparency (transparent areas become white)
- WebP — small AND keeps transparency; supported by every modern browser
- Optional: cap dimensions (e.g. 1280 px) for an even better quality-per-byte result.

How much smaller will my PNG get?
It depends entirely on content. A photographic PNG converted to WebP at target size often lands 80–90% smaller. A screenshot kept as a resized PNG typically shrinks 40–70%. Flat-color graphics with few colors compress extremely well in any mode. Whatever the content, the tool guarantees the output stays at or under the size you set.
