Reduce PNG file size online
Use this PNG compressor online to make PNG images smaller while keeping transparency support and reviewing each compressed result.
Simple local workflow
How local optimization works
Add files, review the local queue, and process each file with the matching browser-based workflow.
Add PNG files
Select PNG images, screenshots, logos, icons, or transparent graphics from your device.
Choose compression balance
Start with the default setting, move left for smaller PNG files, or move right for more conservative output.
Review and download
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.
Transparency-aware
PNG remains the practical choice when a graphic needs an alpha channel, crisp text, or sharp interface edges.
Local by default
Selected PNG images are processed in your browser instead of being uploaded to CompressWise servers.
Built for practical asset work
Why choose this browser-based tool?
A useful image workflow should be clear about privacy, quality, supported formats, and the tradeoffs behind every result.
Built for how PNG is used
PNG compression is different from JPEG compression because PNG often stores screenshots, flat graphics, and transparent images.
Explains why some PNG files stay large
Some PNG files shrink a lot; others are already optimized or need format conversion to become much smaller.
Conservative when quality matters
Higher settings are better for exact colors, text edges, transparent areas, and brand-critical graphics.
Path to target-size compression
If a PNG must fit under 100KB, 200KB, 500KB, or a custom file-size limit, related KB tools are available.
Format and workflow
Choose the right optimization strategy
File type, transparency, markup, and visual detail all affect the best local processing route. Start with the page default, then review the result before publishing important assets.
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.
Keep transparent graphics in PNG
Use PNG when a logo, icon, badge, or overlay needs transparency. Review the output before production use.
Prepare lighter graphics for pages
Optimize PNG files before adding them to websites, documentation, product pages, or app interfaces.
Settings that match the job
Each public tool keeps the main workflow simple while still letting the format use the right local optimization behavior.
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 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 use cases
Prepare lighter image assets for everyday work
A browser-based queue is useful whenever an image asset needs to travel faster, load sooner, or fit within a practical file-size limit.
Product screenshots
Reduce PNG screenshot weight before publishing docs, changelogs, landing pages, or support articles.
Logo files
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.
Privacy by design
Your files should stay yours
The free public tool is designed around a local processing path. That boundary should remain visible as the product grows.
No upload by default
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 originals
PNG compression creates an optimized copy. Keep original files when exact colors, metadata, or archival quality must be preserved.
Current release boundaries
Know the limits before you start
Clear limits make browser-local tools more predictable, especially on mobile devices with less available memory.
- 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.
Questions, answered
Browser-based tool FAQ
How do I compress a PNG file?
Add a PNG image, choose a compression balance, review transparency and colors, then download the smaller optimized PNG result.
How to compress PNG images online?
Add PNG files, use the compression balance, review the optimized output, and download each smaller PNG from your browser.
Can PNG be compressed?
Yes. PNG files can be compressed, but the result depends on colors, transparency, image detail, and whether the file was already optimized.
Is this a PNG compressor online free tool?
Yes. This PNG compressor online free workflow lets you optimize PNG files in your browser without creating an account.
Can I use this as an image compressor PNG workflow?
Yes. If you searched image compressor PNG or compress image online PNG, this page is the PNG-only workflow for screenshots, logos, and transparent graphics.
Can I reduce PNG file size without losing quality?
Light PNG optimization can reduce PNG file size without losing quality visually, but stronger settings may reduce colors or change gradients, shadows, and exact brand colors.
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.
Can I compress multiple PNG files at once?
Yes. You can add a local batch of PNG files and download each completed result separately.
Are my PNG images uploaded?
No. The public workflow is designed to process selected PNG files locally in your browser by default.
When should I use the target KB compressor?
Use the target-size compressor when a form or CMS requires a fixed limit such as 100KB, 200KB, or 500KB.
