Resize and color space
Resize images and adjust color space during conversion or compression in Picmal — five resize modes plus sRGB, Display P3, and Rec. 2020 control.
Image resize
Section titled “Image resize”Turn on resizing to change image dimensions. The same settings apply in both Convert and Compress, so you can drop pixel dimensions while shaving file size in either mode. Five modes to choose from:
| Mode | What It Does | Default |
|---|---|---|
| Percentage | Scale by a percentage of the original size | 50% |
| Fixed Width | Set a specific width; height adjusts to maintain aspect ratio | 1920 px |
| Fixed Height | Set a specific height; width adjusts to maintain aspect ratio | 1080 px |
| Max Dimensions | Constrain to maximum width and height — image is scaled down only if it exceeds either limit | 1920 x 1080 px |
| Exact Dimensions | Resize to an exact width and height | 1920 x 1080 px |
Aspect ratio
Section titled “Aspect ratio”By default Picmal keeps the original aspect ratio. In Exact Dimensions mode you can override that and stretch the image to fit, if you really want squashed faces.
DPI / Resolution
Section titled “DPI / Resolution”Set the DPI (dots per inch) metadata on output images. This changes how big the image lands when printed or dropped into InDesign or Figma. The pixel dimensions stay exactly the same.
Turn on Set DPI in the output settings and pick a preset, or type your own number.
| Preset | DPI | Best For |
|---|---|---|
| Screen | 72 | Web, email, social media |
| Windows | 96 | Windows display standard |
| Retina | 144 | Retina / HiDPI displays (2× 72) |
| Draft Print | 150 | Low-quality print proofs |
| 300 | Standard print quality | |
| High-Quality | 600 | Professional / fine art print |
| Custom | 1–9999 | Any value you need |
DPI applies to both converted and compressed images. Audio and video files ignore it (as they should).
Color space
Section titled “Color space”Convert images between color spaces during processing. Useful when the same photo has to go to a browser, a print shop, and your phone without looking like three different images.
| Color Space | Best For |
|---|---|
| sRGB | Web, email, general screen use (standard) |
| Display P3 | Apple devices, wide-gamut displays |
| Adobe RGB (1998) | Professional print workflows |
| ProPhoto RGB | Professional photography, maximum color range |
| Rec. 709 | HD video and broadcast |
| Rec. 2020 | 4K / HDR video |
If you’re not sure, leave it off. sRGB is the safe bet for almost everything.
Orientation
Section titled “Orientation”| Mode | What It Does |
|---|---|
| Auto-fix | Physically rotates pixels and removes the orientation tag. The image looks correct everywhere |
| Keep tag | Preserves the original orientation tag in metadata. Some apps may not read it correctly |
Pick Auto-fix if your photos are heading to the web or into apps that habitually forget EXIF orientation exists.
