To compress a TIFF to 1MB, 500KB, or 100KB, convert it to WebP and use the quality slider to hit your target. A typical 50MB photography TIFF reaches under 1MB at quality 85. A 10MB scanned document reaches around 200-500KB. The compression comes from switching formats — WebP uses far more efficient compression than TIFF's internal options — not from degrading the image.
There is no "compress TIFF to exactly 2MB" button in any tool. But the quality-to-filesize relationship is predictable enough that you can dial in on your target in one or two attempts.
Why TIFF Files Are So Large
TIFF (Tagged Image File Format) was designed for print production, where every pixel must be preserved. Most TIFF files are uncompressed or use only light compression, resulting in file sizes that are often 10-100x larger than what the same image would be as a WebP or JPG.
A 24-megapixel photograph saved as uncompressed TIFF occupies around 70MB. The same image as WebP at quality 85 occupies about 3-8MB — and looks identical on any screen. The difference is not quality loss; it is format efficiency.
TIFF's internal compression modes (LZW, ZIP, PackBits) reduce this somewhat — typically to 30-50% of uncompressed size. But they still cannot approach what WebP achieves because WebP was built specifically to exploit how human vision works.
How to Hit a Specific Target File Size
There is no single quality setting that guarantees a specific file size because compression ratio depends on image content. But here is a reliable process:
- Start at quality 85 — this is the sweet spot for most images and will get you to under 5% of the original TIFF size in most cases.
- Check the result size — the tool shows before/after sizes. If you need smaller, lower quality to 75 or 70.
- For very small targets (100KB, 200KB) — you may need to combine format conversion with image resizing. A 6000x4000px image will be larger than a 2000x1333px image regardless of compression. Use the image resizer first, then convert to WebP.
Most common email size limits (10MB, 25MB) are easily met by converting any TIFF to WebP at default quality. For platforms with 1MB or 200KB limits, start at quality 80 and adjust.

These are typical output ranges based on common TIFF sizes and image types:
| Original TIFF | WebP Quality 85 | WebP Quality 75 | WebP Quality 65 |
|---|---|---|---|
| 5MB (document scan) | 100-300KB | 60-180KB | 40-120KB |
| 20MB (product photo) | 300KB-1.5MB | 200KB-900KB | 120KB-600KB |
| 50MB (high-res photo) | 500KB-3MB | 300KB-2MB | 200KB-1.2MB |
| 80MB (large format) | 1-5MB | 600KB-3MB | 400KB-2MB |
Line art and technical diagrams compress less than photography at the same quality setting. If your image has a lot of sharp edges and solid colors, expect the higher end of each range.
Common Size Limit Scenarios
Here are specific workflows for common size-limit situations:
- Email attachment under 25MB: Any TIFF to WebP conversion at quality 85 will achieve this. Even a 400MB uncompressed TIFF scan will compress well below 25MB.
- Email attachment under 10MB: Quality 85 handles all but the largest TIFF files. For files over 200MB, lower to quality 75.
- Website upload under 2MB: Quality 80-85 handles most photography TIFF files. For very large originals, try quality 70.
- Social media upload under 1MB: Quality 75-80 usually works. If the output is still too large, resize the image dimensions first using the image resizer.
- Platform limit under 200KB: Resize the image to a smaller pixel dimension, then convert to WebP at quality 75-80.
When Resizing is the Better Answer
Compression only goes so far. A 6000x4000 pixel image at WebP quality 75 will still be larger than a 1200x800 pixel image at quality 85 — because file size depends on both compression efficiency and the number of pixels.
If you have a specific small size target (under 200KB for a thumbnail, under 100KB for a web icon), the practical workflow is:
- Resize the image dimensions to the target display size using the image resizer
- Then convert to WebP at quality 80-85
This two-step approach reliably hits very small targets while maintaining the best possible visual quality at the target size.

Can I compress a TIFF to exactly 2MB?
Not precisely — no tool guarantees an exact output file size because compression depends on image content. But using quality 80-85 on most photography TIFF files will get you to 1-5% of the original size. Adjust quality up or down based on your first result.
What quality setting gets a TIFF under 1MB?
For most photography TIFF files under 50MB, quality 85 achieves under 1MB output. For very large files (80MB+), try quality 75-80. If still too large, resize the image dimensions first.
Is there a maximum TIFF file size the tool can handle?
There is no arbitrary upload limit because files are processed in your browser. The practical limit is your device memory — files up to a few hundred MB work fine on most computers.
What is the smallest a TIFF can get?
For web use, a typical photograph TIFF can reach 0.5-5% of its original size as WebP at quality 80. The theoretical floor for lossy WebP compression is around 50KB for a full-resolution photograph, but that quality level shows obvious artifacts.
