Convert TIFF to JPG on Windows

Insurance scans arrive as TIFF. A vendor sends print-ready TIFF proofs. SharePoint and email want JPEG. Convert TIFF to JPG on Windows with Photos or Paint for one file, FFmpeg for folders. Resize before export when dpi is set for print, not screen.

A folder of forty scan TIFF files at 600 dpi can exceed email limits even after JPEG conversion at full resolution. Cap long edge before share.

TIFF vs JPEG on Windows

Format	Role
TIFF	Scan archive, print pipeline
JPEG	Web, email, CMS

Keep TIFF masters. Export JPEG copies only.

See PNG to JPG on Windows and PDF to JPG on Windows for related image export paths.

Source TIFF	Export approach
Flat scan, no alpha	Photos or FFmpeg, q85
Multi-page TIFF	Split pages in scan software first
Huge dpi	Resize before JPEG

Convert in Photos and Paint

Photos:

1. Open TIFF in Photos.
2. … → Save as or export when available.
3. Choose JPEG quality into deliverables\jpeg\.

Paint:

1. Open TIFF in Paint.
2. Save as → JPEG picture.

Paint and Photos handle one file at a time well. Multi-page TIFF may need FFmpeg or a scan app export per page.

Quality	Use when
High	Client proofs
Medium	Web
Lower	Thumbnails

Compare signature lines at 100% zoom on legal scans before batch send.

Photos may flatten multi-page TIFF to a single view. Use scan software to split pages when each page must be a separate JPEG.

Batch with FFmpeg

winget install --id Gyan.FFmpeg -e

Single file:

ffmpeg -i scan.tiff -q:v 3 scan.jpg

Resize and convert:

ffmpeg -i scan.tiff -vf scale=2400:-2 -q:v 3 scan-2400.jpg

Folder batch:

mkdir jpg-out
Get-ChildItem *.tif,*.tiff | ForEach-Object {
  ffmpeg -i $_.FullName -vf scale=2400:-2 -q:v 3 "jpg-out\$($_.BaseName).jpg"
}

FFmpeg beats opening hundreds of scans in Paint individually.

Keep full/ and web/ folders separate so you can re-export if a client requests higher resolution.

Symptom	Fix
Blurry text after shrink	Start from higher quality JPEG setting
Wrong colors	Convert to sRGB in scan app
Multi-page TIFF	Split pages in scan software first

Scans and print exports

600 dpi TIFF scans produce huge JPEG files at full size. Cap long edge before share.

Issue	Fix
TIFF still huge as JPEG	Lower dpi via resize first
Color shift	Export sRGB JPEG
Multi-page scan	Split in scan app before batch

Scanned TIFF files at 600 dpi are oversized for web. Cap long edge at 2400 px for listing photos, 1920 px for screen review.

See how to compress images on Windows when uploads still fail.

Insurance and HR packets often need legible text at 100% zoom. Spot-check one page before batch send.

For PNG scans with transparency, see PNG to JPG on Windows when the portal requires JPEG only.

Using GetCompress

After TIFF to JPEG export, GetCompress batch-resizes scan folders for portal limits.

• Presets for insurance and HR submission widths.
• Quality presets per attachment policy.
• Preview text legibility on scans.
• Local processing for personal documents.
• Folder monitoring on scanner output.

Use Photos, Paint, or FFmpeg for conversion. Use GetCompress when the whole batch must match one preset.

GetCompress does not replace scan software for deskew or page split. Export JPEG from your scan app or FFmpeg first, then GetCompress for consistent delivery sizing across the whole folder. When a portal rejects the first upload, tweak quality once in the saved preset rather than re-exporting from TIFF unless the source scan changed.

Keep TIFF masters on archive storage. Write compressed JPEG deliverables to a separate folder so you can re-export at higher quality if a client requests it later.
