Frequently Asked Questions

PNG Effects Maker tools are used to manipulate PNG image quality and appearance. The effects tools make optimized images to fit those creative design briefs.

Effects convey mood. For instance, a sepia-toned image is recognizable as “old-fashioned.” Discover the wide variety of PNG Effects Maker tools to get the exact look you want.

Web and app developers, graphic designers and anyone who can upload, adjust settings and download a new image. PNG Effects Maker tools are intuitive, do not require a software download and provide professional results.

Here are a few basic categories:

Your images are never saved to our servers. Image alterations occur in your own browser and can be stored on your computer or mobile device.

Desaturation changes the color and brightness of a PNG image. When colors are converted to grayscale, their brightness determines how dark the image will become. Bright colors, like yellow, will convert to lighter tones of gray and colors with less brightness, like blue or red, will become darker gray. When deep grays are dominant, the entire image appears darker.

Printers use a limited number of colors (CMYK) to make all other colors. To “fake” more than four colors, a dithering filter is used to alter an image pixel size, shape and placement to make printed art look like the original digital art. Next, brightness and contrast are added. The Brightness for PNGs tool adjusts lightness and luminance and the Intensity for PNGs tool adjusts to low, medium or high contrast. Put them together and the printed product will be neither too light nor too dark.

Adjust the color by using the Quality for PNGs tool. It color corrects PNG images by refining the hue and tones, fixes color balance problems caused by flawed lighting and optimizes the image for use.

Consider changing the image to pure black & white. Colors won’t fight each other and shapes, textures or patterns, will become more recognizable. Try the Black & White PNG tool here.

Make the image colors very saturated for a bright, bold look. Or flip the colors in your image using the Invert PNG Colors tool for a cool photo negative effect. For a retro vibe, add a sepia filter for that yellow/brown glow. Check out Interesting PNG Tools for more ideas.

A mirror filter flips an original image along an axis. For an image split along the vertical axis, the left side of the image will look like the original and the right side, like a reverse of it. The Mirror PNG tool is great for creative portraits. Mirroring half of a face, especially in black and white, can make for a stylized composition.

The Skew PNG tool warps images horizontally or vertically, achieving the illusion of 3D space. Flat images jump off the screen or the page. This distortion effect often appears in advertising because it’s difficult to miss.

A PNG image that small may not blow up very well so clone it instead. Exact copies of the image can be arranged into rows, columns or grids and they’ll size up just fine for your wallpaper. You could also use the Zoom PNG tool to enlarge the image while smoothing it out.

A PNG image depicting action that moves from left to right might not be interpreted correctly by Asian readers. Use the Flip PNG Horizontal tool to reorient the image so the action moves right to left and misunderstandings will be avoided.

The Extract Objects by Color tool isolates objects of a single color. Separating a color enables targeted editing without affecting the rest of the image. The Delete PNG Color tool identifies a single color and removes it from the image, which is especially useful for green screens. Both tools single out a color in a few clicks.

A picture is worth a thousand words but when it’s for work, you might want to add a word or two for clarity! The Add Text to PNG tool will overlay a label, caption or longer text on your PNG image for accurate show and tell.

For a grunge style, add a white noise filter to your existing PNG album art for a static or film grain effect. Noise roughens up a PNG image, making it look textured or distressed, which is appropriate for a genre that blends punk, metal and alternative rock!

Whether posting or reacting, social media is all about speed. If it’s not timely, there’s no point. The Add Emoji to PNG tool overlays a text-based emoji onto a PNG, without having to turn the emoji into an image. Users save time while using a universally understood picture language.

Watermark stamps are commonly used to indicate ownership. Watermarks can be translucent or if they interfere with the design too much, can be made transparent. Either way, a watermark laid over key parts of a PNG image is difficult to remove without damaging the image, which discourages reproduction.

The Add Artifacts to a PNG filter overlays JPG or WebP-style artifacts to a PNG image. The effect imitates tv static, corrupted data, computer malfunction or other visual distortions, which is just right for a post-apocalyptic universe.

Dithering is often used in the printing process where all colors are made from four basic colors. The Dither PNG tool applies a pattern of pixels in varying sizes and colors that fool the eye, so the printer-ready image looks like the original. Additionally, the filter compresses the file size.

To achieve a high-resolution, upload the blurred PNG image to the Sharpen PNG tool. Refine the settings until the textures, edges or other features come in focus. Then, download your newly-defined image or copy it to your clipboard.

Try the Blur PNG tool. A blur filter softens and distorts focus to give the impression that the subject is moving, even though the image itself is static. Simply select the percentage of blur desired and apply it to all or part of a PNG image.

Film is made of photosensitive crystals that create a grainy image. It’s easy to achieve the same effect on a digital image. Simply apply the White Noise PNG tool and recreate film texture.

If your PNG image contains sensitive information that must be obscured, one option is to use the Randomizing PNG Pixels tool. Select the part of your image to censor and the tool will automatically apply a large block filter. Or use the Pixelate PNG tool for a smaller, mosaic appearance. Both tools enable you to redact text, obscure faces and cover identifying details for privacy

Sure, if you’re looking for more definition. To apply an outline, border, or as it’s known in graphic designer language, a stroke, check out the Add Stroke to PNG tool. Strokes provide increased visibility as the image is made distinct from its background.

Let’s say you have a logo that needs some depth. The Shadow PNG tool applies drop shadows, which makes the 2D logo look 3D. “But don’t those shadows affect the image transparency,” you might ask? No. The image may look darker but the background is unaffected and retains its transparency.

Sci-fi or neon titles often make use of a backlight for dramatic effect. Using the Glow PNG tool, select your desired amount of backlight and where to apply it, to achieve that futuristic look.

Use the Stencil PNG tool to easily transform any PNG image into a stencil or pattern. Upload the stencil into the vinyl cutter and make signs, wall art, stickers and other personalized crafts with cutouts.

Polaroid photos shoot out of the camera and develop by themselves inside an iconic white frame. The Polaroid PNG tool frames digital images in the same way for a retro feel, which is especially great for family photos.


Use cases

Photographer’s Assistant

To sell his work, a photographer constructs an online portfolio of high-resolution photos. His livelihood depends on retaining the rights to his work, so he overlays his logo on every picture, using the Watermark PNG tool. Afterward, he uploads his watermarked images to the Quality PNG tool, to reduce file sizes, without losing visual quality. As a result, his protected portfolio looks great and even loads faster for better customer experience.

Designer Graphics

A graphic designer requires a negative of a black-on-white logo for a new marketing campaign. The Invert PNG Colors tool reverses the logo colors, producing a PNG image that looks like a photo negative. Then she uploads the white-on-black image to the Sharpen PNG tool to make the colors distinct. The new logo looks great on the website redesign, which requires excellent visibility in dark mode.

Game Designer

A game developer is building a pixel art game with classic, low-resolution design. The Pixelate PNG tool can help him to achieve his design brief in a few clicks. After uploading the PNG image, he can control the size and placement of pixels to create the mosaic or blocky images associated with 8- or 16-bit art.

Wedding Whiz

Wedding photographers edit their shots to ensure that the happy couple have wonderful memories of their special day. Photographers can correct focus using the Sharpen PNG tool but editing for mood is also part of the job. The Contrast Editor for PNGs tool can be used to reduce contrast which sets a soft, vintage or romantic feel, appropriate to the occasion.

The Face of K-Pop

K-Pop produces endless content about its stars, or idols, who are renowned for their “glass skin”. Blemishes simply aren’t allowed and makeup can only do so much. Every Korean graphic designer has a blur filter in their toolbox to smooth skin appearance and keep idols looking good.
