Resize Image

Resize JPG, PNG or WEBP images to exact dimensions — keep the aspect ratio and pick the output format.

Original: . Resizing happens entirely in your browser.

How to use the Resize Image

  1. Upload an image. Choose a JPG, PNG or WEBP file.
  2. Set the size. Enter width/height; keep aspect ratio locked to avoid distortion.
  3. Download. Pick a format and download your resized image.

About the Resize Image

Resize Image changes the width and height of a JPG, PNG, or WEBP file to an exact pixel size, right inside your browser. You type the dimensions you need, decide whether to keep the original proportions locked, and the tool redraws the picture at the new size. It is built for the moments when a number, not a vibe, is the requirement: a profile photo that must be 400 by 400, a marketplace listing capped at 2000 pixels on the long edge, or an upload form that rejects anything wider than a fixed limit. No account, no watermark, no waiting on a queue.

Reach for it whenever a platform publishes a precise spec. Social channels are the obvious case: a square 1080 by 1080 post, a 1280 by 720 video thumbnail, a banner with fixed proportions. The same applies to passport and ID submissions that demand an exact pixel size, product images for a store grid, or large camera photos that are simply too big for a website and slow the page down. Shrinking an image to the dimensions it will actually display at is also one of the cheapest ways to make a site load faster on mobile, because the browser no longer downloads pixels it will never show.

Under the hood the tool uses the browser's canvas to redraw your photo through resampling. When you shrink an image it discards pixels; when you enlarge it the algorithm has to invent pixel values by averaging neighbours, which is why scaling down stays crisp while scaling up softens detail. Keep the aspect-ratio lock on and the height fills in automatically from the width so nothing stretches; switch it off only when you truly need an exact box and do not mind the content squashing. The quality slider controls JPG and WEBP compression on export, letting you trade a little sharpness for a much smaller file.

Everything happens locally. Your file is read with the browser's FileReader, drawn onto a canvas, and exported again without ever being sent to a server, so the image never leaves your device. Two honest caveats worth knowing: resizing never adds real detail, so a tiny picture blown up large will look soft no matter the tool, and DPI does not matter here at all. Screens and upload forms count pixels, not dots per inch, so a 3000 by 2000 image is the same file whether it is tagged 72 or 300 DPI. Focus on the pixel dimensions and you will hit the spec every time.

Frequently asked questions

How do I resize an image to an exact pixel size?

Upload your JPG, PNG, or WEBP, turn off the aspect-ratio lock if you need a precise box, then type the exact width and height in pixels and resize. With the lock on, enter one value and the other is calculated to keep the proportions.

Will resizing reduce my image quality?

Scaling down is essentially lossless and keeps photos sharp because the tool only removes pixels. Enlarging is different: the algorithm has to invent new pixels, so an upscaled image will look softer the more you stretch it beyond its original size.

Does this change the DPI for printing?

No. This tool sets pixel dimensions, which is what screens, social platforms, and upload forms actually read. DPI only affects physical print size, so for web and digital submissions you should focus on pixels, not dots per inch.

Are my images uploaded to a server?

No. The resizing runs entirely in your browser using the canvas, so your file is processed on your own device and never sent anywhere. That makes it safe for private photos, IDs, and confidential documents.

Why does my image look stretched after resizing?

That happens when the aspect-ratio lock is off and the width and height you entered do not match the original proportions. Re-enable the lock, or choose dimensions in the same ratio as your source, to resize without distortion.

Split PDF Like a Pro: Extracting Page Ranges and Separating Every Page

By the Super Simple Digital Tools Team · Updated June 2026

Most people meet a PDF splitter for the first time because something will not send. An email bounces over a size cap, an upload portal rejects the file, or a colleague only needs three pages out of forty. Splitting solves all of these by letting you keep exactly the pages that matter and discard the rest. The skill worth learning is not the clicking, it is deciding which of the two split modes fits the job in front of you.

Use the range-extract mode when you want one continuous chunk of a document: a single chapter, the pages a client must sign, or the appendix a reviewer asked for. You name a start and end page and the tool hands back one tidy PDF. Use the split-every-page mode when a file is really many documents stacked together, which is typical of batch scans where a feeder turned a tray of separate forms into one long PDF. That mode gives each page its own file so you can rename, sort, or file them independently.

Page numbering trips people up more than anything else, so check it before you commit. The tool counts the way your viewer does, with the first visible page as page 1, ignoring any printed numbers on the page itself. A document whose printed page 1 is actually the third sheet because of a cover and a blank will still be split by position, not by the ink on the page. Scroll to the exact pages you want, note their positions in the viewer, and use those numbers.

Quality is rarely a worry with a proper splitter because the operation copies page objects rather than rebuilding them. There is no second round of JPEG compression and no font substitution, so a 600-dpi scan comes out at 600 dpi and a vector chart stays crisp at any zoom. The one thing splitting does not always carry over is document-level structure such as the bookmark outline or form field links, since those reference the whole original. If an intact outline matters, keep the master file and treat the split pieces as derivatives.

Finally, think about where the work happens. A browser-based splitter that runs on your device keeps the file off any server, which is the safest choice for contracts, financial statements, and anything with personal data. The trade-off is that it cannot reach inside an encrypted PDF, so unlock password-protected files first and save a plain copy to split. With the right mode chosen, the page numbers verified, and privacy handled, splitting becomes a ten-second task you can repeat with confidence.

  • Open the PDF in any viewer first and note the position of each page you need, since the splitter counts from page 1 by position, not by the numbers printed on the pages.
  • For a batch of scanned forms that arrived as one file, use the split-every-page mode and unzip the result, then rename each single-page PDF as you file it.
  • If your goal is shrinking an email attachment, extract only the range you need rather than splitting everything, so you end up with one small file instead of a folder of pages.
  • Unlock and re-save any password-protected PDF as an unencrypted copy before splitting, because encrypted page contents cannot be read or separated.
