Overview
Open Upscale Image to make a larger PNG from a JPG, JPEG, PNG or WebP image with AI upscaling. Add up to 10 images per batch; each file must be 20 MB or smaller and contain no more than 2,000,000 pixels. Processing may run on your device, a server or a cloud GPU, depending on routing and availability. Sign in and review the credit charge before processing. Online processing requires an internet connection. Keep your original, then check the downloaded PNG’s dimensions and details before using it.
AI upscaling makes a larger PNG by generating additional image detail. Processing may run on your device or online. Scale offers 2 and 4, but the saved dimensions can vary by processing mode. Compare the downloaded image with your original and verify its width and height.
When to use
- Use Upscale Image when you need a larger PNG copy of a JPG, JPEG, PNG or WebP image. Keep the original so you can compare details that matter.
- Check both file size and pixel area before adding an image. For example, a 1000 × 1500 image contains 1.5 million pixels; a small file in megabytes can still exceed the pixel limit.
How to use
Add JPG, JPEG, PNG or WebP images within the limits: up to 10 files per batch, 20 MB per file and 2,000,000 pixels per image. Check width × height as well as file size; for example, 1000 × 1500 is 1.5 million pixels. Images with dimensions the tool cannot read are rejected. Reduce an oversized image’s dimensions before adding it.
Choose 2 or 4 in Scale, review the credit charge, then start processing. The selected scale is not applied consistently across processing modes: a 2 selection can still produce a 4x result, and some modes may resize the input first. Check the downloaded PNG’s width and height when you need an exact size.
Wait for processing to finish, preview the result and download the PNG. Open it at the size you plan to use and check its width and height, faces, small lettering and edges against the original. PNG and WebP inputs can become opaque, so check the background if transparency matters. Keep the original if the enlargement changes a detail you need.

Examples & use cases
A designer preparing a portrait for a profile card.
Enlarge a portrait for a profile card
The JPG is 1200 × 1600 pixels, or 1.92 million pixels, so it is within the input area limit. It looks too small in the card layout, and the face needs a careful check at the intended display size.
JPG to PNG
- Scale:
- 2
- Choose Scale 2 to request an enlargement. Because the processing path can affect the actual dimensions, check the downloaded PNG’s width and height.
- Compare the face and edges with the original at the card’s intended display size. Keep the original if a detail looks different.
Expected outcome
A larger PNG to review in the card layout. Check its saved dimensions and compare the face with the original before using it.
A presenter preparing a small diagram for a slide.
Enlarge a diagram for a presentation slide
The 900 × 900 PNG is within the pixel limit, but its small labels and line edges need to be checked at the larger slide size.
PNG to PNG
- Scale:
- 2
- Choose Scale 2 to request the enlargement; this choice does not guarantee an exact 2x output size.
- Inspect the lettering and line edges in the downloaded PNG at slide size. Compare important labels with the original before presenting them.
Expected outcome
A larger PNG to assess in the slide. Check the labels and line edges at the intended size, and compare important text with the source.
A shop owner preparing a product photo for a larger listing preview.
Prepare a product photo for a larger preview
The 900 × 1200 WebP is within the pixel limit. The shop owner wants a larger copy and needs to check the product outline before updating the listing.
WebP to PNG
- Scale:
- 4
- Choose Scale 4 to request the larger result. The selected value does not guarantee final dimensions on every processing path, so check the saved PNG’s width and height.
- Inspect the product outline and other important edges at the intended preview size. Compare them with the original before replacing the listing image.
Expected outcome
A PNG enlargement to review for the listing. Confirm the saved dimensions and inspect the product outline against the original before using it.
More ways to use it
- A print designer checking an enlargement for a planned print.: The source image is small for the intended print size, and important faces, lettering and edges need to be assessed before ordering. Choose Scale 4 to request a larger result, but verify the saved dimensions because the processing path affects the outcome. A larger PNG to inspect at the planned print size. For an important print, make a small test print before ordering the final size. Scale: 4.
- A presenter preparing a low-resolution reference photo.: The photo needs to appear larger in a presentation, but the enlargement should not be treated as proof that missing details are accurate. Choose Scale 2 to request a smaller enlargement than Scale 4, while keeping in mind that the processing path may not honor the selection. A larger PNG to compare with the source. Check faces and text carefully, and avoid relying on changed details where accuracy matters. Scale: 2.
Troubleshooting
The image is rejected because it exceeds 2,000,000 pixels.
Try this: Reduce the image dimensions with Resize Images Online: Set Width and Height, then add it again.
What to expect: An image with readable dimensions that meets the pixel-area limit and the other file limits can pass the pixel preflight.
The downloaded PNG dimensions do not match the Scale choice you expected.
Try this: Download the PNG and check its width and height.
What to expect: The saved dimensions show the actual result. Scale 2 is not honored by every processing path, and the browser fallback uses fixed 4x processing.
Privacy
Processing may run on-device or online. Online processing uploads the image. Uploaded files and results may remain available after processing. See https://mioffice.ai/privacy for current retention and file-handling details.
Frequently asked questions
How do I decide whether an enlarged image is good enough to print?
Inspect the PNG at the size you plan to print, focusing on faces, lettering and sharp edges. More pixels alone do not guarantee more faithful detail. For an important print, check a small test print before ordering the final size.
Will AI upscaling recover the original missing detail?
Not reliably. Treat added detail as generated content, especially around faces and text. Compare the enlarged image with the original before relying on it where accuracy matters.
What image formats can I upscale, and what format is the download?
Supported inputs are JPG, JPEG, PNG and WebP, and the output is PNG. If your destination needs another format, use Convert Images to JPEG, PNG or WebP to make a copy and check the saved file.
Can I upscale multiple images at once?
Yes. You can add up to 10 supported images per batch. Each file must be 20 MB or smaller and contain no more than 2,000,000 pixels.
What should I check if an image will not upload?
Check the file type, file size and pixel area. Inputs must be JPG, JPEG, PNG or WebP, no larger than 20 MB and no more than 2,000,000 pixels. Images with dimensions the tool cannot read are rejected. Reduce the dimensions of an image that exceeds the pixel limit before adding it again.
Does choosing Scale 2 or 4 guarantee those exact output dimensions?
No. Scale offers 2 and 4, but a 2 selection can still produce a 4x result, and some processing modes resize the input first. Check the downloaded PNG’s width and height.
Can I upscale an image without losing quality?
The tool creates a larger PNG, but it does not promise unchanged detail or quality. Keep the original and compare the enlarged result before using it, especially where faces, lettering or edges matter.
Are my uploaded images kept private?
Online processing uploads your image. On-device availability does not guarantee that every image stays local. Uploaded files and results may remain available after processing. See https://mioffice.ai/privacy for current retention and file-handling details.
Can I upscale images without uploading them to a server?
On-device processing is available on compatible devices, but routing and availability determine where a particular image is processed. Sign in and review the credit charge before starting. Don’t assume every image stays on your device. The online server path requires sign-in and an internet connection.
Can AI upscaling improve a low-resolution or pixelated image?
The tool can create a larger PNG from a supported input, but it does not promise to remove pixelation or restore accurate missing detail. Compare the output with the original and inspect the areas you need to use.
How can I upscale an image without making it blurry?
The tool does not guarantee that an enlargement will preserve sharpness. Open the downloaded PNG at the size you plan to use, compare faces, lettering and edges with the original, and keep the source if an important detail changes.
Will an upscaled PNG keep a transparent background?
Not necessarily. PNG and WebP inputs can become opaque even though the download is PNG. If transparency matters, check the saved image’s background before using it.
