How to reduce PNG file size online

Add PNG screenshots, logos, or transparent graphics, then review colors and transparency before downloading.

01

Add PNG images or screenshots

Select PNG images, screenshots, logos, icons, or transparent graphics from your device.

02

Choose a PNG compression balance

Start with the default setting, move left for smaller PNG files, or move right for more conservative output.

03

Review transparency and download smaller PNG files

Check transparency, edges, colors, and output size before saving the optimized PNG files.

Reduce PNG file size

Compress PNG size for screenshots, logos, UI captures, and transparent graphics with a PNG-focused browser workflow.

Compress PNG online free

Use a PNG-focused browser workflow for screenshots, logos, UI captures, and transparent graphics.

Keep transparent PNG graphics when possible

PNG remains the practical choice when a graphic needs an alpha channel, crisp text, or sharp interface edges.

Why use this PNG compressor online free

This page focuses on PNG compression for screenshots, logos, transparent graphics, and web assets.

Built for screenshots, logos, and transparent graphics

PNG compression is different from JPEG compression because PNG often stores screenshots, flat graphics, and transparent images.

Understand why some PNG files stay large

Some PNG files shrink a lot; others are already optimized or need format conversion to become much smaller.

Compress PNG without visible quality loss when possible

Higher settings are better for exact colors, text edges, transparent areas, and brand-critical graphics.

Move to target-size compression for strict KB limits

If a PNG must fit under 100KB, 200KB, 500KB, or a custom file-size limit, related KB tools are available.

PNG compression strategy

Choose the right PNG compression strategy

PNG results depend on transparency, color count, and sharp edges, so the best setting depends on what the image needs to preserve.

Screenshots

Compress screenshots and UI captures

PNG is useful for crisp text, interface edges, and flat-color captures. Results depend on image detail and color count.

Transparency

Keep transparent graphics in PNG

Use PNG when a logo, icon, badge, or overlay needs transparency. Review the output before production use.

Web assets

Prepare lighter PNG files for web pages

Optimize PNG files before adding them to websites, documentation, product pages, or app interfaces.

PNG compression settings that match the job

Use stronger compression when file size matters most, and use conservative settings when exact colors or transparent edges matter.

Smaller

Move left when file size matters most

Lower settings may reduce colors to create smaller PNG files. Review gradients, shadows, and brand colors before publishing.

Default

Start with a conservative PNG pass

The default balance is a safe starting point for most PNG images before trying stronger optimization.

Quality

Move right for exact edges and colors

Higher settings are better when transparent details, sharp text, or brand colors matter more than the smallest file.

Common PNG use cases

Best uses for PNG compression online

Use the PNG compressor when screenshots, logos, documentation images, or transparent assets need smaller files.

Screenshots and UI captures

Reduce PNG screenshot weight before publishing docs, changelogs, landing pages, or support articles.

Transparent logos and graphics

Create lighter PNG logo copies while keeping the original file for brand-critical uses.

Transparent graphics

Optimize overlays, badges, icons, and UI assets that need an alpha channel.

Documentation images

Compress annotated PNG captures before adding them to guides, help centers, and internal docs.

Form uploads

Use PNG compression when an upload form accepts screenshots or graphics but asks for a smaller file.

Format decision

Compare PNG needs against JPEG or WebP when a photo saved as PNG remains too large.

Private by default

Compress PNG online without uploading by default

The public PNG compressor is designed to process selected PNG files locally in your browser.

Local PNG processing

Selecting a PNG file should not send the image to our server. The public tool is designed around browser-local processing.

No account required

You can compress PNG images without creating an account, adding billing details, or saving a cloud history.

Keep your original PNG files

PNG compression creates an optimized copy. Keep original files when exact colors, metadata, or archival quality must be preserved.

Current release boundaries

PNG compression limits to know before you start

Some PNG images shrink a lot, while detailed screenshots or already-optimized files may have less room to compress.

  • This page accepts PNG images only.
  • A local batch can contain up to 10 images to keep memory usage predictable.
  • PNG compression results vary by color count, transparency, detail, and whether the file is already optimized.
  • Lower quality settings may use color reduction, which can change gradients, shadows, and exact brand colors.
  • Photos saved as PNG may stay large; JPEG or WebP can be a better format for photo compression.
  • Metadata retention controls are not exposed yet. Keep your original files when metadata must be preserved.

Can PNG images be compressed without losing transparency?

The workflow is designed for PNG files, including transparent graphics. Review the result before using it in a final design or production asset.

Why is my PNG still large after compression?

PNG size depends heavily on colors, transparency, and image detail. Some PNG files are already optimized or need a different format to become much smaller.

Is PNG or JPEG better for smaller file size?

JPEG is usually better for photos. PNG is better for screenshots, crisp graphics, and transparency.

Should I convert PNG to WebP instead?

WebP can be smaller for many web assets, but PNG is still useful when transparency, compatibility, or exact graphics matter.
