MORE THAN A BIGGER FILE

A thoughtful finish, down to the details.

Enlarge, refine and compare. A few clear choices, with your originals kept safe.

2K, 4K, 8K. Your proportions.

Use a long-edge preset or 2×, 4× and 8× enlargement. Exact output pixels appear before processing; no stretching or surprise crop.

Real AI, right on your device.

An ESRGAN Slim neural model estimates texture and edges locally. Choose Fast mode for a quick resize when you want speed.

Your idea of natural.

Deep clean and reduce source noise, then tune sharpness, brightness, contrast and saturation with a live adjustment preview. Start with Natural, Soft portrait, Illustration or Text presets.

A small batch. A smoother workflow.

Work on up to six images, processed one at a time to control memory. Download each result or collect completed images in a ZIP.

Private by design.

Photos are never uploaded to an enhancement server. Model files come from this site on first use. Cancel without changing your originals.

A comparison you can actually use.

Move the before-and-after slider, use a center crop at output pixel size, and check the real dimensions before downloading.

FROM FIRST PHOTO TO FINISHED IMAGE

Three small steps. A bigger possibility.

  1. 01

    Choose your photo

    Add a JPEG, PNG, WebP or another supported still image. Try a sample to get familiar with the controls.

  2. 02

    Choose size and detail

    Pick 2K, 4K, 8K or an enlargement factor. Use Fast or AI detail, then adjust the finishing touch.

  3. 03

    Compare and download

    Check the slider and detail crop. Save a JPEG, PNG or WebP, or download the completed batch as a ZIP.

More pixels can help. Lost information is still lost. AI may estimate plausible textures and can change fine detail. Enhancement cannot guarantee recovery of faces, unreadable text or severely blurred information. Keep your originals and inspect the result.

YOUR NEXT SMALL WIN

Small photo. More room for your next idea.

Choose a size, enhance locally and compare the real result before downloading.

Photo Enhancer & Image Upscaler: questions & answers

Useful answers. Clear next steps.

At a glance

Enhance and upscale photos in your browser. Choose 2K (2,048 px), 4K (4,096 px) or 8K (7,680 px) along the longest edge, or enlarge both dimensions by 2×, 4× or 8×. Aspect ratio is preserved. Fast mode uses high-quality resizing and photo adjustments; AI detail runs an ESRGAN Slim neural model locally in tiles. Deep clean and reduce noise before enlargement. Adjust brightness, contrast, saturation and sharpness with a live scaled preview. Apply changed settings to generate a fresh download. Compare actual results, inspect a center detail crop, and download JPEG, PNG or WebP. Up to 6 images, 350 MB combined input, no fixed pixel or megapixel upload cap, and an output budget of 64 MP / 8,192 px per side. Device memory can impose lower limits. AI estimates detail and cannot guarantee recovery of missing information.

How do I enhance a photo or upscale it to 2K, 4K or 8K?

Choose an image or try a sample. Pick 2K, 4K, 8K or an enlargement factor, then Fast or AI detail. Deep clean and noise reduction work before enlargement; brightness, contrast, saturation and sharpness finish the output. A scaled adjustment preview updates as you tune the controls. Press Enhance to create the full-size result. After changing settings, Apply & download generates a fresh file with the selected dimensions; ZIP is available after all changes are applied. File size in bytes also depends on format, quality and image content.

What do 2K, 4K, 8K and 2× / 4× / 8× mean?

The 2K, 4K and 8K buttons set the longest edge to 2,048, 4,096 or 7,680 pixels, keeping aspect ratio. They do not force a 16:9 crop. The 2×, 4× and 8× choices multiply both source dimensions. Exact output pixels are shown before processing. A preset below the source size reduces it; a factor exceeding the 8,192-pixel side or 64 MP output limit is rejected.

Does the AI mode really use a neural network?

Yes. AI detail loads a pinned ESRGAN Slim 1.0.0 model and TensorFlow.js runtime from this site, then runs tiled inference on this device. It chooses a 2×, 4× or 8× model to suit the output. Above 8× total enlargement, AI runs at 8× and the remaining scale uses quality resampling. Fast mode performs high-quality resizing and adjustments without AI. AI is loaded only when requested.

Can enhancement recover blurry faces or unreadable text perfectly?

No. More pixels do not guarantee authentic missing detail. AI may estimate plausible textures, change small features or introduce artifacts. Severe blur, tiny text, damaged areas and highly compressed sources may remain unclear. Compare at output pixel size, keep the original and review faces, lettering and edges before use.

Which formats, batch sizes and limits are supported?

JPEG, PNG, WebP, BMP, GIF first frame and browser-supported AVIF inputs are supported. Export JPEG, PNG or WebP, individually or in a ZIP. Up to 6 files share a 350 MB input budget. There is no fixed pixel or megapixel upload cap; output is limited to 64 megapixels / 8,192 pixels per side and 350 MB combined. Browser memory and codec support can lower practical limits. SVG and HEIC are not accepted.

How fast is it, and can I stop a large job?

Fast mode avoids AI downloads and neural inference. AI downloads a small model and runtime on first use, processes one image at a time in small tiles and reports progress. Large 8K jobs may take minutes and can exceed a device’s available memory. Cancel terminates the worker, preserving originals and completed results. Try Fast mode, 2K or a smaller batch if processing fails.

Are photos uploaded, and what happens to transparency or metadata?

Photo files and result images remain in the browser; they are not uploaded to an enhancement service. Model and runtime assets download from this site. PNG and supported WebP output keep alpha; JPEG flattens transparency on white. New exports omit source EXIF metadata. Animated sources become a still first frame. Compare previews are scaled; the download keeps the displayed pixel dimensions.
