Convert TIFF to ICO the right way
Every image conversion involves a small trade-off between quality, file size, and compatibility. Here's how to make the choice deliberately, not by accident.
-
1
Drop your TIFF files or click to browse
The drop zone above accepts single images or batches. Free-tier uploads are limited to 10 MB per file — enough for phone photos and standard web images. Pro handles files up to 1 GB and batches of up to 20 at once. Filenames are preserved, and the new extension is appended automatically.

2
Confirm the quality preset (if the target supports one)
ICO conversions default to a sensible middle ground — high enough that nothing visible is thrown away, low enough that the file isn't oversized. If you're preparing for print, pick a higher quality; for a web thumbnail, drop it. If the target format is lossless (PNG, TIFF, or WebP-lossless), there's no quality slider — every pixel is preserved.

Convert and download
The output is ready in a couple of seconds for a single image, or a few seconds for a batch delivered as a ZIP. Both the source you uploaded and the ICO output are permanently deleted from our servers within 30 minutes — nothing is retained, backed up, or shared with anyone.
What's actually happening in a TIFF-to-ICO conversion
The pixel data in your source is decoded, held briefly in memory as a raw bitmap, and re-encoded into the target format's container. Along the way, we preserve the colour profile embedded in the source (TIFF usually carries sRGB; some phone cameras save wider gamuts), any alpha channel where both formats support it, and EXIF metadata where relevant.
If the target format lacks something the source has — say, transparency in a PNG being converted to JPG — that data flattens onto a background before encoding. You'll never lose visible pixels silently; where a trade-off happens, we default to the most common expectation for that specific format pair.
Things people wish they'd known before converting
- You can't recover quality that's already gone. Converting a low-quality JPG to a lossless PNG makes a bigger file that preserves the same compression artifacts — the "improvement" is imaginary.
- Watch what happens to transparency. Converting from a format with an alpha channel (PNG, WebP) to one without (JPG) forces a background colour behind the transparent pixels. Preview the result before you commit.
- Strip EXIF before sharing publicly. Camera photos carry GPS location, capture time, and device model in EXIF. If you're posting the image somewhere public, remove metadata during (or after) the conversion.
- Resize before converting when you can. A 24-megapixel source doesn't need to be a 24-megapixel WebP for a website. Resize first, then convert — the file will be a fraction of the size, and quality at display resolution will be identical.
When TIFF to ICO is the right move
Real reasons people run this conversion — grounded in specific problems, not vague benefits.
Meeting a website or CMS format requirement
WordPress rejects some source formats out of the box. Squarespace, Ghost, and most e-commerce platforms have their own preferred image formats. If the upload button greys out or throws an error, a quick conversion to ICO usually fixes it — no plugin needed.
Sharing across ecosystems
Some image formats are ecosystem-specific — HEIC belongs to Apple, WebP has patchy support on legacy Windows apps, and some tools still balk at anything newer than JPG. Converting to ICO means the person receiving the file doesn't have to install anything to open it.
Preparing for a form or portal submission
Passport portals, visa applications, university forms, and job platforms often specify an exact format and file-size ceiling. If the requirement is ICO, this is the conversion. If they specify size too, run the compression tool afterwards to hit the target byte count.
Getting the right format for a design tool
Figma prefers PNG or SVG for exported assets. InDesign expects TIFF, EPS, or high-quality JPG for print. Canva takes almost anything but produces cleaner results with lossless sources. Converting your image to what the tool actually wants avoids the "why does this look pixelated" back-and-forth.
Reducing file size for email or messaging
A 24-megapixel PNG is 20+ MB. Converting to a well-compressed ICO typically brings that under 3 MB with no visible change on a normal screen. Perfect for sliding under Gmail's 25 MB attachment cap, WhatsApp's compression, or a form's "under 5 MB" rule.
Archiving photos or scans
For long-term storage, a stable, widely-supported format matters more than pixel-perfect quality. ICO is a reasonable archival choice for TIFF sources when the goal is "openable in 10 years on whatever device exists then." Bonus: batch convert the entire folder in one pass.
Every conversion happens on TLS-encrypted uploads, on isolated per-request workers, with both the source and the result auto-deleted within 30 minutes. No ads, no watermarks on paid tiers, no metadata mined for training.
