Free Online Image Editor — Resize, Convert & Filter (No Upload)

You need to do something quick to a photo — make it smaller to email, convert a PNG to a JPG, brighten a dim shot, or turn a batch of pictures black-and-white. You shouldn't have to install a heavy app or upload your photos to a website that keeps a copy.

EditMyStuff's image editor runs entirely in your browser. You drop in JPG, PNG or WebP files, make your changes with live preview, and download the result — single images or a whole batch as a ZIP. Nothing is uploaded, nothing is stored, and there's no account.

What you can do

The editor covers the everyday edits people actually need:

• Adjust — brightness, contrast, saturation, hue and blur, each with a live slider.
• Filters — one-tap black-and-white, sepia and invert.
• Rotate & flip — 90° either way, plus horizontal and vertical flip.
• Resize — set an exact width or height (aspect ratio locked), or scale by 25/50/100/200%, capped so a huge image can't freeze your tab.
• Convert formats — export as PNG (lossless, transparent), JPG (smaller, with a quality slider) or WebP (modern and compact).

Everything previews instantly as you drag the sliders, so you can see exactly what you'll get before you download.

Edit a photo, step by step

1. Open the editor. Go to the image editor and drop your image in — or click to choose one. It loads locally; nothing uploads.
2. Make your edits. Use the side panel (a bottom sheet on mobile) to adjust, filter, rotate, flip or resize. The preview updates live.
3. Compare before and after. Toggle the compare view and drag the divider to see the original next to your edit.
4. Pick a format. Choose PNG, JPG or WebP, and set the quality for JPG/WebP.
5. Download. Your image saves with an _edited suffix so it never overwrites the original.

Edit many photos at once

This is where a browser editor really saves time. Drop in up to 50 images, edit one until it looks right, then hit Apply edits to all — the same adjustments, filters, rotation and resize are applied to every image. Download them together as a ZIP.

Resize 10 holiday photos to 800px wide and convert them to WebP in one pass, without uploading a single one.

It's perfect for prepping a folder of images for a website, an email, or a marketplace listing that wants a specific size.

Undo without fear

Every change is tracked per image, so you can step back and forth through your edits and experiment freely — brighten too far, undo, try a different filter. Each image keeps its own history.

Why client-side matters for photos

Photos are personal. A face, a location in the background, a document you snapped — uploading them to an online editor means handing copies to a company you don't control. EditMyStuff never does that: the editing happens on your device using your browser's own graphics engine, the same one this page is drawn with. Your images never travel over the network, and closing the tab clears everything.

It's the same privacy-first approach behind the rest of EditMyStuff's tools — the PDF editor and image-to-PDF converter included.

Wrapping up

For quick, private photo edits — resizing, converting, filtering, rotating, in single shots or whole batches — you don't need an app or an account. Open the free image editor, drop in your photos, and download exactly what you need.
