Ever tried uploading an ID photo to an official website or job application portal, only to get an error saying ‘File size must be under 1MB’? You don’t need expensive software like Photoshop to shrink your image in seconds without losing noticeable quality.
At a Glance
- Web compression tools (TinyPNG): Instantly compress JPG and PNG files by 50–80% without installing any software (free tier allows up to 20 images per session, 5MB per file).
- Windows Paint: Open the image and press
Ctrl + Wto reduce percentage or pixels at zero cost.- Samsung Galaxy Gallery: Go to Edit > More > [Resize] and choose a 20% to 80% ratio to save a copy directly.
- Files over 10MB: These exceed the TinyPNG free limit (5MB), so resize them first using Windows Paint or iLoveIMG before compressing.
How to Compress Images Instantly in Your Browser
When you have no time to download and install software, browser-based compression tools are the fastest option. These services typically use color quantization techniques and strip unnecessary metadata.
Much like neatly packing a suitcase to save space, these tools cut file size by 50% to 80% with virtually no visible loss in image quality.
| Service | Supported Formats | Key Features & Free Tier Limits |
|---|---|---|
| TinyPNG | WebP, PNG, JPG | Free for up to 20 images per session, max 5MB per file |
| iLoveIMG | JPG, PNG, SVG, GIF | Select 25%, 50%, or 75% reduction presets with free resizing tools |
| Squoosh | JPG, PNG, WebP, etc. | Google open-source tool with real-time compression preview, no sign-up needed |
However, if your original image exceeds 10MB, you cannot upload it directly to TinyPNG’s free tier (5MB cap per file). In that case, resize the resolution first using iLoveIMG or built-in Windows tools.

How to Reduce File Size for Free Using Built-In Windows Tools
If your PC runs Windows 10 or 11, you can reduce file sizes without spending a cent using pre-installed tools.
The first method is Microsoft Paint. Right-click the image and open it in Paint, then press Ctrl + W to open the ‘Resize and Skew’ dialog. Make sure ‘Maintain aspect ratio’ is checked, then reduce the percentage to 50% or 70%, or lower the pixel count directly and save the file.
The second method is the Photos app. Open the image in Photos and click the three dots (···) at the top, then select [Resize image]. You can manually adjust the width and height in pixels, or slide the quality down to 60–70% to hit your exact target size.
How to Shrink Photos on Samsung Galaxy Without Installing Apps
If you need to submit a phone photo directly from mobile, you do not need third-party apps either. Samsung Galaxy’s built-in Gallery app comes with a built-in resize feature.
Open the photo in the Gallery app and tap the pencil icon (Edit) at the bottom. Then tap the three dots (More) and select [Resize].
Choose your desired resolution—20%, 40%, 60%, or 80% of the original—and save it as a copy. This keeps the original intact while producing a file in the hundreds of kilobytes.
If you have a large photo you need to submit right now, press Ctrl + W in Windows Paint or use a web compressor to shrink it in under 10 seconds.
