14 quick PNG utilities — convert, compress, resize, edit transparency and recolor
PNG is the format you reach for when you need crisp edges and real transparency — logos, icons, screenshots and diagrams. But the everyday jobs around PNG files usually mean hunting for a converter site or firing up an editor: turning a JPG into one, shrinking a bloated export, or dropping the background out of a product shot. These 14 tools handle each of those tasks directly in your browser.
Every tool works locally with JavaScript and the HTML canvas, so your PNGs are never uploaded to a server. That keeps screenshots, unreleased artwork and client files private, and it means there is no upload wait, no file-size cap and no watermark on the result. Convert, compress and edit as many images as you like.
PNG's lossless compression preserves every pixel, which is ideal for graphics with sharp lines and flat color but tends to produce large files for photographs. That is why several tools here focus on trimming size (Compress PNG) or converting to a lighter format (the JPG and WebP bridges), while others lean into what PNG does best — clean transparency, borders, rounded corners and crisp recoloring. Pick the one that matches the task and it opens instantly, no account required.

What Each Tool Does
Every tool below opens instantly, needs no account, and processes your data locally in your browser. Here is what each one is for:
JPG to PNG
Convert JPG photos into lossless PNG files, ready for transparency edits or crisp on-screen graphics. Open the JPG to PNG →
WebP to PNG
Turn modern WebP images back into universally supported PNG files for editing or older software. Open the WebP to PNG →
Compress PNG
Reduce PNG file size with smart color quantization while keeping edges sharp and transparency intact. Open the Compress PNG →
Resize PNG
Scale a PNG to exact pixel dimensions or a percentage, with aspect-ratio lock to avoid stretching. Open the Resize PNG →
Rotate PNG
Turn a PNG 90, 180 or 270 degrees to fix its orientation in a couple of clicks. Open the Rotate PNG →
Flip PNG
Mirror a PNG horizontally or vertically for reflections and layout tweaks. Open the Flip PNG →
Add Border
Add a solid colored border of any width around a PNG to frame it cleanly. Open the Add Border →
Round Corners
Round the corners of a PNG to any radius, keeping the area outside the curve fully transparent. Open the Round Corners →
Add Text
Overlay custom captions or labels onto a PNG with control over font, size and color. Open the Add Text →
Make Transparent
Make a chosen color transparent to knock a flat background out of a PNG. Open the Make Transparent →
Add Background
Fill a transparent PNG with a solid color so it displays correctly on any surface. Open the Add Background →
Remove Background
Erase the background from a PNG to isolate the subject on transparency. Open the Remove Background →
Grayscale
Convert a PNG to black and white while preserving its transparent areas. Open the Grayscale →
Invert Colors
Invert every color in a PNG to create a photo-negative effect. Open the Invert Colors →
How to Choose the Right Tool
Start with the converters when you just need the format: JPG to PNG and WebP to PNG bring images into PNG for lossless editing. If a file is too heavy, Compress PNG trims it without visible loss, and Resize PNG changes its dimensions precisely. For layout and presentation, use Add Border, Round Corners and Add Text. The transparency group is the heart of PNG work — Make Transparent and Remove Background knock out a background, while Add Background does the reverse. Grayscale and Invert Colors handle quick recoloring. Every tool keeps the alpha channel intact unless you deliberately fill it.
Frequently Asked Questions
Do PNG files keep their transparency after editing?
Yes — every tool here preserves the alpha channel, so transparent areas stay transparent. The only exception is Add Background, which intentionally fills them with a color you pick.
Are my PNGs uploaded to a server?
No. Every tool runs entirely in your browser using the HTML canvas, so your images never leave your device.
Why is my PNG so large, and can I make it smaller?
PNG uses lossless compression, which keeps quality perfect but bloats photographs. Use Compress PNG to shrink it, or convert to JPG or WebP for photo-heavy images.
Can I convert a JPG into a real transparent PNG?
Converting to PNG gives you the format, but a JPG has no transparency to recover. Use JPG to PNG first, then Make Transparent or Remove Background to knock out a background.
