The tool is set up like a mini editor: you upload a single file, the resize/flip/rotate controls appear, and you apply changes with one action button. It’s built for the common “I just need the right size” workflow, not full design work.

• 1) Upload your image: Drag and drop or click to upload one file. Supported formats are .png and .jpg/.jpeg.
• 2) Open the editor: After selecting a file, the editor panel shows three tabs: Resize, Flip, and Rotate.
• 3) Choose how you want to resize: In the Resize tab, you can resize as a percent (slider) or by dimensions (enter width and height).
• 4) Pick the output format: Under Save image as, choose Original, PNG, JPG, or WEBP. This is handy when you want a smaller file or a more modern format.
• 5) Flip or rotate if needed: Use Flip Horizontally / Flip Vertically, or rotate clockwise/counterclockwise in 45° increments.
• 6) Apply changes: Click Resize Image to process and generate your download.
• 7) Download result: On the results screen, you’ll see the filename and file size plus a Download button. If you want to tweak more, hit the reload button to resize another image.

Resize by percentage (fast and hard to mess up)

The percentage mode is the “quick win” option. You drag a slider between 20% and 100%, and the tool scales the image relative to its original size. That’s perfect when your goal is simply “make it smaller” while keeping the same look and proportions.

And it’s more practical than it sounds. If a platform rejects your upload because the file is too big, dropping to 75% or 60% often reduces both pixel dimensions and file size enough to pass. You don’t have to guess new width/height values, and you don’t need to do math in your head.

Resize by exact dimensions (pixels) when you need precision

Sometimes you’re not resizing for file size—you’re resizing for layout. Maybe your e-commerce theme needs 1200×1200 product images, or your blog header must be exactly 1600×400. In the By dimensions mode, you can enter a specific height and width as numbers.

This is also the mode you’ll use when a client or platform gives you a requirement like “upload must be 1080px wide” or “thumbnail must be 300×300.” You type it, preview it, save it. No extra steps.

Flip horizontally or vertically (mirrors without drama)

Flipping is surprisingly common: selfies, camera scans, product photos, or designs that need a mirrored version. In the Flip tab, you can use Flip Horizontally or Flip Vertically with one click.

And because flip is separate from resize, you can do both in one pass. For example, flip horizontally for a better composition and then resize to a standard width for your website.

Rotate in 45° steps (great for crooked phone photos)

Rotation isn’t limited to 90° jumps. The tool rotates clockwise or counterclockwise in 45° increments, which is ideal when your photo is slightly angled. It’s the difference between “still looks off” and “clean enough for publishing.”

So if you scanned a document at an angle or took a quick photo of a whiteboard, you can straighten it without opening a full editor.

Export as PNG, JPG, or WEBP (format choice matters)

Under Save image as, you can keep the original format or export as PNG, JPG, or WEBP. This is useful because resizing and format choice often go together. You might resize a transparent PNG but export to WEBP for a smaller web-friendly file, or keep it as PNG if you need transparency.

JPG is usually fine for photos, PNG is better for graphics and transparency, and WEBP often gives you a solid quality-to-size balance for modern web use. Having the choice built into the resize flow saves time.

Resizing is usually not the “real job.” It’s the annoying step blocking the real job. Here’s where this tool earns its keep.

• Website uploads: Resize oversized hero images so pages load faster and upload limits stop complaining.
• Marketplace product photos: Standardize width and height for consistent grids (especially for square thumbnails).
• Social media prep: Quickly adjust a photo for posting, then rotate it to fix odd camera orientation.
• Blog headers and featured images: Set exact pixel dimensions so your theme doesn’t crop unpredictably.
• Document photos: Rotate and straighten a slightly crooked scan, then resize for easier sharing.
• Design handoff: Export to WEBP for web performance, or PNG for crisp graphics with transparency.
• Quick mirroring: Flip an image horizontally for layout balance or to match a design direction.
• Portfolio and CV attachments: Reduce image size before attaching to emails or forms that have strict limits.

Example #1: You’re uploading product photos to a store platform that wants consistent squares. You open one image, switch to By dimensions, set width and height to 1200×1200, and export as JPG for a smaller file. The result looks consistent across the catalog, and you’re not fighting random cropping.

Example #2: You took a photo of a printed document, but it’s slightly tilted and upside down. You rotate it in 45° steps until it looks straight, then resize to a smaller percentage so the file is easy to email. One run, problem solved.

Example #3: You have a PNG graphic that needs to stay transparent, but the original is huge. You resize by percentage to 60% and keep the format as PNG. It stays crisp, it stays transparent, and it’s far lighter than before.

Sure, you can resize images in a desktop editor, or you can upload them to a design tool and export again. But that’s overkill when you’re doing simple transformations. The real choice is about speed, precision, and how many steps you want.

Decide whether you’re optimizing for pixels or file size

If a platform requires an exact size, go straight to By dimensions. If the platform only cares about “under X MB,” start with percentage because it’s faster. After that, choose a format that matches the content: JPG for photos, PNG for crisp graphics, WEBP for modern web delivery.

Keep quality expectations realistic

Resizing down is generally safe. Resizing up (making a tiny image big) can look blurry, because you’re stretching pixels. So if you’re trying to “improve quality,” resizing usually won’t do it. Instead, start from the highest-quality original you can find, then resize down to your target.

Use rotation before resizing when alignment matters

Rotating can slightly change how the image fits inside its bounding box. So if you’re fixing a crooked scan, rotate first, then set your final width/height. It’s a small order-of-operations thing, but it saves you from redoing the resize.

Choose WEBP when the image is for a website

If the image will live on a web page and you don’t need legacy compatibility or special editing, WEBP is often a great export choice. You’ll usually get a smaller file with solid visual quality, especially compared to large PNGs.

• Spelling check: If you export to JPG, remember it doesn’t support transparency.
• Consistency: For product grids, pick one dimension set and stick to it for every image.
• Preview habit: After rotate/flip, re-check composition before you lock in your final size.
• Safety: Keep a copy of the original if you’re doing multiple iterations.
