Struggling to shrink a JPEG under 50KB? To compress a JPEG to 50KB, simply upload your image to Smallpdf's Compress PDF tool, choose your compression level, and export back to the image format — it takes less than 30 seconds and works with any JPEG file. Here's a simple method that works, no expensive software or complicated tools required!

How to Compress JPEG to 50KB Online (Free and Fast)

Upload, Compress, Export as JPEG

1. Go to our Compress PDF tool and upload your JPEG. You can do this by either dragging and dropping your image into the upload area or by clicking “Choose Files” to select one from your device.
2. Select the “Basic” option for medium compression or “Strong” for an even smaller file size and click “Compress” to reduce the file size. Note that Strong compression is a Smallpdf Pro feature—start with a 7-day free trial.
3. Once the compression is complete, click “Export As” and choose “Image (.jpeg).”
4. Choose “Convert entire pages” and then click “Convert”.
5. That's it! Click “Download” to get your newly compressed JPEG.

Tip: Use Strong Compression (Pro) if You're Just Over 50KB

If your JPEG is still slightly over 50KB after Basic compression, Strong compression will reduce the resolution more aggressively to hit that target size. While there's some quality loss, it's often the best way to get under the 50KB limit.

Why Choose Smallpdf to Compress JPEG to 50KB

Fast and Reliable Compression

Our compression algorithm consistently delivers results in under 30 seconds, and you can process multiple images at once for batch compression needs.

Secure Processing and Privacy

All uploaded files are automatically deleted from our servers after one hour, and we use HTTPS/SSL encryption to protect your images during processing.

Works on Web and Mobile

Smallpdf also offers a mobile app for iOS and Android users, allowing you to compress or convert your JPEG files from anywhere.

When using Smallpdf on your phone, you can import any image from your gallery or scan an image directly within the app.

While using the Smallpdf mobile app as a JPEG compressor, you'll have to start by manually converting your image into a PDF. Doing this isn't difficult: you can simply run your file through our Convert JPEG to PDF tool before opening the PDF compressor.

From there, you'll follow the same process you would on a computer. Simply compress your PDF, convert it back to JPEG format, and save the resulting file.

Downloading the Smallpdf mobile app isn't the only way to use our services on mobile devices. You can also access our PDF compressor and other tools by visiting our website on your device's browser.

How Smallpdf Compression Works

When you upload your JPEG file to our compression tool, we convert it into a PDF, compress it as much as possible, then convert it back to JPEG format. JPEGs aren't the only images that Smallpdf can compress — our tool also handles PNG and BMP files, and other popular image formats.

Compress JPEG to Other Sizes (100KB, 200KB, and More)

Need a different file size? Our compression tool works for various size targets beyond 50KB. Whether you need images for email attachments, web uploads, or social media, you can adjust compression settings to hit your target.

Tips to Hit an Exact File Size Target

1. Start with Basic compression first — it often gets you close to your target without quality loss.
2. If you're still over your limit, try Strong compression for more aggressive size reduction.
3. For very specific size requirements, you may need to adjust image dimensions before compression.

What Else Can You Do With Your Files?

If you’re already using Smallpdf as an online photo compressor, you might be wondering what else our tools can do. With the help of Smallpdf, you can:

• Edit PDFs: Do you want to make changes to a PDF file? That’s what our PDF Editor is built for. This feature allows you to add annotations, highlights, images, and shapes to your documents. Smallpdf Pro users can also edit text in their PDFs with this tool.
• Chat with PDFs: We leverage AI technology to give you new ways to interact with PDF files. While using Chat With PDF, you can ask your document questions about the information it contains.
• Summarize PDFs: Another AI-powered feature is our AI PDF Summarizer, which generates an easy-to-read summary of any document you upload.
• Extract PDF pages: If you only need some pages included in a PDF document, you don’t have to keep the entire file. You can use Smallpdf’s Extract PDF tool to save individual pages from a PDF.
• Convert PDFs to other file formats: With Smallpdf’s tools, you can save PDFs as Word, Excel, and PowerPoint documents. You can also change any documents in these file formats to PDFs while using Smallpdf.

Troubleshooting: JPEG Still Not Under 50KB? Try These Tips

Can I Compress to Exactly 50KB?

Compression algorithms can't guarantee exact file sizes, but our tools typically get within 5-10KB of your target. For the best chance of hitting 50KB, try Strong compression if your file is close.

Will Image Quality Drop at 50KB?

Some quality loss is inevitable when compressing to very small sizes like 50KB. Strong compression reduces resolution more noticeably than Basic, but the trade-off is significantly smaller file sizes.

Is Online JPEG Compression Secure?

Yes — we use HTTPS encryption during upload and processing, and all files are automatically deleted from our servers within one hour of upload.

Can I Process Multiple JPEG Images?

You can upload and compress multiple images in the same session, making it easy to batch process several JPEGs to 50KB at once. Ready to compress your JPEGs perfectly? Start your free trial to access all Smallpdf tools including Strong compression.
