Last updated on Oct 27, 2025

Compare compression types in Adobe Photoshop and select the best format for image quality, file size, and intended use.

Compression type

Description

Use case

RLE (Run Length Encoding)

Uses lossless compression to encode repeated data sequences efficiently.

Compresses simple graphics in standard Windows file formats.

LZW (Lempel-Ziv-Welch)

Uses lossless compression to retain all image data while reducing file size.

Compresses images with large areas of solid color in TIFF, PDF, GIF, and PostScript.

JPEG (Joint Photographic Experts Group)

It uses lossy compression to reduce file size by removing image detail. You can adjust the quality using the menu, slider, or by entering a value from 0 to 12.

Compresses continuous-tone images like JPEG, TIFF, PDF, and PostScript photographs. Prints only on Level 2 or later PostScript printers and may not support plate separation.

CCITT (Consultative Committee for International Telegraphy and Telephony).

Uses lossless compression designed for black-and-white images.

Compresses scanned documents or line art in PDF and PostScript.

ZIP

Uses lossless compression similar to LZW to reduce size without losing quality.

Compresses images with flat color areas in PDF and TIFF.

Compression formats in Photoshop

Format

Reason to use

Image content

Compress photos with JPEG. Use LZW or ZIP for graphics with solid colors.

Quality requirements

Choose RLE, LZW, ZIP, or CCITT to preserve exact image data.

File size constraints

Use JPEG for the smallest file sizes (with some quality loss).

Output medium

Choose a format based on display or print requirements.

WebP format support in Photoshop

WebP works well for web pages and supports both lossless and lossy compression. Use the quality slider to adjust compression and choose whether to keep metadata. WebP files are smaller than most traditional formats but still look sharp. Explore the compression settings to fine-tune image quality and file size.
