Fast and RefineThere’s the “Fast” radio button for quick formatting edits and retouches. Here you’ll find your usual crop, straighten, resize and automatic tools like auto-contrast, auto-fix, heal and red eye. For artistic flourishes, “Fast” also includes focal point bokeh-like blurring and color splashing for creative effects.For more dialed-in adjustments, the “Refine” radio button provides granular sliders for color, contrast, blur, sharpen, smooth and even double exposure effects with another image.
Filters, Stickers and other Special EffectsThe real fun in Pixlr starts with its library of special effects. Try out interesting filters like creative, unicolor, vintage, or watercolor with the “effect” and “stylize” buttons.Pepper your photo with graphical extras like overlays, borders and stickers. You can even add your own text.
Note: Although Autodesk has recently retired its Pixlr desktop apps for Mac and Windows, legacy versions are still available online. Keep in mind that these will no longer be updated but these are still excellent free photo editing tools with a wide variety of interesting filters. Better yet, using their effects and filters no longer require a Pixlr account.
