Start with the settings for your task. All files are processed locally in your browser.

01 / CHOOSE

Choose a photo to compress

Choose an image or a supported PDF page. Your original stays untouched.

02 / FINE-TUNE

Reduce image size in KB

For one image, choose a KB target. For a batch, choose format, quality and width; there is no batch byte target.

03 / SAVE

Compare and download

Check the actual file size and dimensions, then download your result.

Choose the right settings for your image

CorvexsDigital is a free image compressor, resizer, and format converter for people preparing uploads, email attachments, product photos, and website images. It supports individual images and batches of up to 20 files, processed sequentially in your browser. Choose a target for a strict upload limit, or select No limit to evaluate a chosen quality setting. The tool reports the real output size rather than promising that every image can meet every limit.

Work backwards from the upload requirements

Suppose a form accepts JPG under 200 KB and requires at least 600 pixels in width. Choose JPG, set the target, then check the result’s dimensions as well as its bytes. If you allow smaller dimensions to reach the target, the tool may go below the destination’s minimum. Disable that option when dimensions must be preserved. Check the receiving service’s instructions; these example values are not universal upload rules.

For a shop thumbnail, useful composition and readable detail matter more than a specific number of bytes. Crop in an editor first if you need a square. CorvexsDigital preserves the original ratio and does not enlarge a small source. For a screenshot, inspect the smallest meaningful text. If it becomes hard to read, increase the allowed size or choose a more suitable format.

Understand the limits before choosing a file

Input files are limited to 20 MB. Raster images are limited to 40 megapixels; a large decoded image can use much more memory than its saved file size suggests. PDF pages are rendered separately at a bounded resolution. Some damaged files or uncommon codecs cannot be decoded. Self-contained SVGs are supported; scripts and external references are rejected. Use a simpler exported copy when a source cannot be read.

Compare formats rather than repeating exports

JPG suits many photographs but turns transparent areas white. PNG keeps transparency and crisp edges, but its quality slider is disabled because this encoder does not use it. WebP can be useful for web images, provided the destination accepts it. Export each comparison from your master file. Raising the quality of an already damaged copy cannot restore missing detail.

The target-size field uses decimal KB: 200 KB means 200,000 bytes. A rounded display in another application can differ, so check the actual byte limit and output dimensions. Batch mode has quality, format and width controls but no target-KB setting; select one image when you need a specific byte target.

Know what local processing means

The image workflow does not upload your selected file. A browser needs normal hosting requests to load the tool and its conversion libraries. Support messages are separate and go through the contact provider. Re-encoding does not constitute certified redaction: private details visible in the picture stay visible. Keep originals and verify the output before uploading it elsewhere.

For a repeatable workflow, start with the 100 KB and 200 KB guide, compare PNG and JPG, or troubleshoot a rejected upload. Short clips have their own video compressor.

A FEW USEFUL DETAILS

Before you compress
and share a file.

Choose settings for your destination, then inspect the result before using it.

Explore the technology guides ↗

Is browser-based image and video compression automatically GDPR compliant?

CorvexsDigital processes selected images and videos locally on your device without uploading them for compression. This reduces file transfers, but does not by itself establish GDPR compliance. Website hosting, Google Analytics, and contact-form services have separate data-processing implications.

How does local compression help UK and EU businesses protect client files?

Local compression avoids sending selected media files to a remote compression service. This can help freelancers, agencies, and businesses reduce unnecessary transfers of client material. You must still follow your organisation’s security policies and assess whether your device and workflow are suitable for sensitive files.

Is CorvexsDigital free to use in the UK and EU?

Yes. The current tools are free and require no registration, subscription, or payment details. Technical limits still apply: images are limited to 20 MB and 40 megapixels, and videos to 100 MB, five minutes, and 4K input. Browser compatibility and available device resources also affect processing.

Can I compress PNG, JPG, WebP, and MP4 files in my browser?

Yes. The image tools support PNG, JPG, and WebP. MP4 video input is supported when your browser can decode its codec. Image exports are JPG, PNG, WebP or browser-supported AVIF; video exports are WebM or MP4 where supported. Processing avoids a compression upload, but speed depends on file size, settings, browser, and device. Video re-encoding can take approximately the duration of the clip.

How do I compress an image to 100 KB or 200 KB?

Select your image, choose a target, and press Compress image. The tool reduces encoding quality and, if allowed, dimensions until it finds an output at or below the limit. It shows the actual result size and warns if the target cannot be reached. KB means 1,000 bytes here.

What is the best image compressor for my photos?

Choose a tool that accepts your format, lets you control dimensions and quality, and shows the actual result before you download. Local processing is useful when you want to avoid sending photos to a compression server. For product photos, inspect fine detail; for logos, check transparency. No single format or setting is best for every image.

Can I compress an image to 5 MB?

Yes: enter 5000 in Target file size KB and check the result after compression. This tool uses 1 MB = 1,000 KB. Enable smaller dimensions only when your destination allows them. Complex images may miss the target. Read the 5 MB, email and product-image guidance for more detail.

Will the image look exactly the same?

JPG and WebP compression can discard detail. Very small targets can also require fewer pixels. Compare the preview and check the downloaded file at its intended display size. Your original file is never overwritten.

Which format should I choose?

JPG is widely compatible for photos and puts transparent areas on a white background. PNG keeps transparency but ignores the quality slider, so meeting a small limit may require resizing. WebP is another option when your destination accepts it. Output size depends on the image and browser.

Can I use it for online application forms?

Use the form’s exact file-size, format, and dimension requirements. This tool preserves aspect ratio and limits width; it does not crop to passport-photo dimensions or certify that a photo meets an agency’s rules. Check the downloaded dimensions before submitting.

Where do my images go?

Selected files are processed in your browser and are not uploaded. Remove the image or close the page to end the session. The hosting service still handles normal website requests; see our privacy notice. HEIC/HEIF, GIF, SVG, and PDF input are supported alongside JPG, PNG, and WebP. PDFs export one selected page as an image, SVG is rasterized, and animated files export as a still image. Source metadata is not preserved.

Make every image count.
