FAQ
Is this safe?
Yes. Compression runs locally in your browser — no uploads.
Why is PNG still big?
PNG is lossless. Biggest savings usually come from resizing or switching to WEBP/JPG when possible.
How to compress PNG on iphone (for faster loading)
- 1) Select your PNG (it stays on your device).
- 2) If the PNG is large, set Max width to ~1600px (optional).
- 3) Click Compress & Download (lossless PNG re-encode).
- 4) Compare file sizes and keep the better result.
- 5) If you need massive savings, consider PNG → WEBP (separate tool).
How-to
This page helps you bulk compress by compressing PNG on iphone (for faster loading).
Important: PNG is a lossless format. That means “quality” does not work like JPG. The biggest size reductions usually come from resizing, simplifying the image, or using a more efficient format.
What this tool does: it re-encodes your PNG locally and optionally resizes it. Depending on how the original PNG was produced (app/export settings), re-encoding can sometimes reduce size a bit — but not always.
Resize is the main lever. If your PNG is 4000px wide but displayed at 1200px, resizing can cut the file size dramatically while still looking perfect on the page.
For WordPress/Shopify: smaller PNGs speed up uploads and reduce page weight. For logos/icons with transparency, PNG is often needed — keep dimensions tight.
If you still need the file much smaller: consider converting to WEBP (keeps transparency in modern browsers) or using SVG for simple logos.
Workflow tip: compress one example, compare, then batch the whole folder (Pro ZIP) to keep things consistent.
Privacy note: everything runs in your browser. Nothing is uploaded to a server.
Common mistakes
- Expecting big savings without resizing (PNG is lossless).
- Uploading huge dimensions for small display sizes.
- Using PNG for photos (JPG/WEBP is usually better).
- Not testing transparency on the real background color.
