Key features
Private conversion without the usual trade-offs
This png to ico converter is built for the actual job: take a PNG logo that a browser tab or Windows shortcut will not use, write an ICO copy, and leave with the file—without a signup funnel.
Batch without a paywall
Select one PNG or a whole group for png to ico. Every item has its own status, in-page preview, retry action, ICO download, and a shared ZIP option when more than one icon is ready to leave the page.
Favicon sizes in one file
Default output packs 16, 32, 48, and 256 pixel layers so a website favicon and a Windows shortcut can share one .ico. Uncheck sizes in Advanced when you only need a single square.
No round-trip upload delay
Because the browser already decodes PNG, conversion starts as soon as you choose files. There is no extra Convert click after an upload spinner and no holding pen that expires the download in an hour.
What is it?
What is PNG to ICO Converter?
PNG to ICO conversion decodes a Portable Network Graphics still and writes square icon layers into a Windows ICO container. People search png to ico after a logo export lands as .png and a website, installer, or shortcut picker still asks for favicon.ico.
The formats are not clones. PNG is a general still that may be any rectangle. ICO is a Microsoft icon file that stores one or more square images, commonly 16 through 256 pixels, so Windows and browsers can pick a layer. This tool creates a practical PNG-in-ICO copy: default 16+32+48+256, transparency kept, and no extra crop besides fitting the mark in a square.
Format guide
Choose ICO when
You need a favicon.ico, a Windows 11 shortcut icon, or an installer that lists .ico rather than a PNG asset.
Keep PNG when
You still want the editable web graphic, a non-square layout, or a store listing that asks for PNG or WebP. Convert a copy rather than deleting the source.
Supported: input .png; output .ico. Related: HEIC to JPG, PNG to JPG, PNG to WEBP, JPG to PNG, and HEIC to PNG.
How to
How to convert png to ico
The whole png to ico workflow stays on one page. There is no separate upload screen, processing dashboard, or account handoff. Choose files, watch the queue, and download without leaving this converter.
Step 1
Select PNG files
Choose one or multiple .png logos or UI marks, or drop the group into the converter. Conversion starts automatically on this page.
Step 2
Convert locally
The browser resizes each PNG into square layers and writes an ICO on this device. Per-file png to ico progress lets successful icons finish even if another item fails.
Step 3
Preview and download
Open the in-page preview to confirm the mark, download any completed ICO immediately, or package the batch as one local ZIP.
Why choose it
Why choose this png to ico converter?
It is intentionally narrower than a general editor: fewer decisions before a png to ico conversion, clearer privacy boundaries, and output you can download immediately.
No signup detour
Open the page, choose files, and download. There is no email gate or account step between the PNG and this png to ico output, which is the delay most upload converters add before the first result.
Better failure isolation
One damaged or unusually encoded PNG does not block the rest of the queue. Completed ICO files remain available while failed items can retry without starting the whole batch over.
Clear output choice
Use this page when you specifically need a Windows icon or favicon.ico. Use PNG to JPG for email photos, PNG to WEBP for website stills, and the homepage HEIC converter when the source is an iPhone photo.
Private by architecture
The conversion path uses browser memory and local object URLs. Standard page requests still reach the host, but image bodies do not power a conversion API or appear on a public recent icons wall.
Pro tips
Pro tips for a usable ICO
The useful choice for png to ico is which squares to pack, not a pile of hidden sliders. Use the receiving app and the importance of the source file to decide sizes and whether to keep the PNG.
Common limitation An ICO can be smaller on screen than a PNG and still be correct. Square fitting does not restore vectors, extra frames, or metadata the browser decoder does not expose.
Start from a square PNG at least 256×256: ICO layers are squares. A wide screenshot will letterbox on a transparent field rather than stretch.
Keep the PNG master: An ICO is a compatibility copy for Windows and browser tabs. Keep the original when you still edit vectors or a larger web asset.
Transparency survives here: PNG alpha is drawn into each layer. Do not flatten to white unless you want an opaque tile.
Photoshop does not export ICO natively: Search often suggests a plugin. This tab writes the container without an install.
Use cases / recommended settings
Recommended settings for real-world jobs
Default 16+32+48+256 covers most png to ico jobs. Change sizes only when a checklist asks for 64 or 128, or when you only need a 16-pixel tab icon.
Default pack 16+32+48+256 · Keep alpha
Drop a favicon.ico in the site root

FAQ
Frequently Asked Questions
Direct answers about free bulk conversion, Windows 11, favicon.ico, Photoshop, quality, privacy, transparency, sizes, and URL uploads.
How do I convert png to ico free online?
Open this page, choose one or several PNG files, wait while the browser writes ICO copies locally, then download each file or one ZIP. You do not need Photoshop, an ICO plugin, or an account for this path.
Is this png to ico converter free?
Yes. The converter is free online with no signup wall and no paid daily quota. Practical limits come from your device memory and the 250 MB per-file safety ceiling, not from a conversion credit system.
How do I convert png to ico on Windows 11?
Open this page in Chrome, Edge, or Firefox on Windows 11, choose the PNG from File Explorer, wait for the preview, and download the ICO. Paint can open a PNG but still does not write a multi-size icon container by itself.
How do I make a favicon.ico from a PNG?
Use a square PNG of your logo, convert it here with the default 16+32+48+256 pack, download the .ico, and place it in the website root or link it from your HTML head. This page is the favicon job, not a general photo compressor.
Does converting png to ico lose quality?
Each layer is a lossless PNG packed into the ICO. Shrinking a 512 mark to 16 pixels discards detail because 16×16 cannot hold it, not because JPEG compression ran. Keep the PNG master when you still need the large original.
Can I convert png to ico in bulk?
Yes. Select multiple .png files in one picker action or drop a group on the converter. Each item shows its own preview, retry control, and ICO download, and finished files can pack into one local ZIP.
Are my PNG files uploaded to a server?
No conversion upload is required. Decoding, square resizing, ICO packing, previews, and ZIP packaging run in this browser tab. Ordinary HTTPS page requests still reach the host, as the Privacy Policy explains.
Does the ICO keep a transparent background from PNG?
Yes. Layers are encoded as PNG-in-ICO with an alpha channel. Transparent pixels stay see-through instead of filling white. Verify the preview if your source used a checkerboard that is actually baked into the PNG.
What sizes should I include in an ICO?
The default pack is 16, 32, 48, and 256. Tabs often use 16 or 32. Desktop shortcuts use 32 or 48. High-DPI Windows wants 256. Add 64 or 128 in Advanced when an installer checklist asks for them.
Do I need Photoshop to convert png to ico?
No. Photoshop does not export ICO without a plugin. This page converts inside the tab you already opened, without a desktop install or a Creative Cloud login.
Is there a file-size limit for png to ico?
Each input has a 250 MB hard safety ceiling. There is no paid file-count cap. A huge poster PNG can still fail if the tab runs out of memory—retry on a desktop with more RAM, or start from a 512 square instead.
Can I convert a PNG from a URL?
Not on this page. We only convert files you select from this device so image bytes never go to a conversion API. Download the PNG first, then drop it here. Cloud-drive and URL fetch converters are a different product.
Is PNG-in-ICO compatible with old Windows?
PNG-in-ICO works on Windows Vista and later, including Windows 10 and 11. Windows XP expected BMP DIB icons. We do not emit that older BMP-only container. If you still support XP, use a dedicated legacy icon editor.
Can I convert png to ico without losing the original pixels?
The 256 layer keeps a square fit of your source. Smaller layers are resized copies inside the same file. We do not keep a 2000-pixel landscape at original width because ICO is a square icon format, not a photo archive.
