Drop image here to compress to 75KB
JPEG, PNG, WebP, AVIF, HEIC. All processing stays in your browser.
Want to compare against a different limit? Change the target field above, no need to drop the file in again.
Five steps is all it takes. Everything runs in your browser so there is no waiting for an upload or server processing.
Set your target
The target is pre-set to 75KB. Adjust it to any value if your portal has a different limit.
Drop your image
Drag and drop a JPEG, PNG, WebP, AVIF, HEIC or HEIF file onto the tool. No upload happens, the file stays on your device.
Quality search, dimension scaling if needed
The tool runs a quality search first. Only for an unusually detailed image does it also need to reduce pixel dimensions. This runs in a background worker, so the tab stays responsive.
Fine-tune without starting over
Change the target or switch between JPEG and WebP afterward and the tool recompresses automatically.

The 75KB target is most prevalent on educational and examination portals. Below are the four most common places where applicants encounter this limit.
Entrance exam registrations
National and state-level exam portals in India commonly require applicant photographs between 50KB and 80KB. The 75KB target covers most of these requirements.
University admission portals
Undergraduate and postgraduate application systems at many universities cap the student photograph at 75KB to 80KB. This tool reaches that target reliably.
Online scholarship forms
Scholarship portals operated by state governments and private institutions often set a 75KB ceiling on uploaded applicant photos and supporting documents.
Competitive exam applications
UPSC, SSC and other competitive exam portals regularly update their photo requirements. 75KB is a target that fits many of their current specifications.
When you are compressing identity documents and passport photos for official submissions, privacy matters. Decoding uses the Canvas API, or a dedicated decoder for HEIC and HEIF files, and the compression itself runs via WebAssembly in a background Web Worker. All of it happens inside your browser. No image data is sent to any server at any point.
You can verify this yourself. After the page has fully loaded, turn off your Wi-Fi or disconnect your ethernet cable. Drop your image into the tool. It will compress and download successfully with no internet connection, because no network request is needed.
Using 50KB when the portal actually allows 75KB
If a portal's stated maximum is 75KB or higher, use the larger number. The extra size budget gives the quality search meaningfully more room to work with, for no downside.
Choosing JPEG for a transparent scan
If the source PNG has a transparent background, JPEG will fill it with a solid color. The tool warns about this and offers a one-click switch to WebP, which keeps transparency.
Assuming quality adjustment alone can't reach 75KB
At 75KB it almost always can. Dimension scaling is a rare fallback here compared to tighter targets like 20KB or 30KB, so if the result panel shows a scale factor below 100%, that's a sign the source was unusually large or detailed.
Outputting WebP for a portal that only accepts JPEG
Exam and university portals were almost always built around JPEG specifically. If a submission gets rejected and the reason isn't clear, switching the output format to JPEG is the first thing to try.
Re-dropping the file just to compare a different target
That's no longer necessary. Changing the target size field after a result already appears recompresses automatically using the same cached image.
Ignoring the warning that the target wasn't fully reached
Uncommon at 75KB, but for an unusually detailed source image the tool may not hit the target at an acceptable quality. When this happens it still delivers its best attempt but flags it on the result panel.
The 75KB limit appears most commonly on university admission portals, national entrance exam registrations such as JEE, NEET and similar systems, and state government scholarship applications. It is a middle-ground threshold that gives acceptable image quality while keeping storage requirements modest for large-scale portal systems.
At 75KB, a compressed photograph will noticeably retain more detail and have fewer compression artefacts than the same image at 50KB. If your portal accepts either 50KB or 75KB, always use the larger target. The additional 25KB allows the search to settle on a higher quality setting, resulting in sharper edges and more accurate skin tones.
There's no artificial ceiling, the search can use any quality from 1 to 100. At 75KB, a typical phone photo generally lands on a meaningfully higher quality than the same photo would get at 50KB or below, since the extra size budget gives the search more room before it has to compromise.
Rarely. The tool always tries quality reduction first. Only for an unusually large or detailed source image, where even the lowest quality setting still overshoots 75KB or looks too degraded, does it step the pixel dimensions down, roughly 75%, 50%, 35%, 25% and then 15% of the original size, re-running the quality search at each smaller size.
The tool accepts JPEG, PNG, WebP, AVIF, HEIC and HEIF as input. The output is JPEG or WebP only, never PNG. For exam portals and university submissions, always choose JPEG as the output format. It has universal acceptance and will not be rejected by any portal.
Yes. The tool works in Chrome, Safari, Firefox and Edge on both Android and iOS. On iPhone, photos are usually saved as HEIC files. The tool decodes HEIC and HEIF natively in the browser, so you do not need to convert your photo first.
Reducing dimensions alone does not guarantee a specific file size output. The actual byte size depends on image content, format and encoder settings. This tool searches for the highest quality setting, up to 100, that still produces a file under 75KB. You get the maximum possible quality for the target, not just a guess.
Yes. The tool keeps the decoded image cached, so adjusting the target size field or clicking JPEG or WebP after a result already appears triggers an automatic recompress rather than asking you to drop the file in again. Useful for comparing 75KB against 50KB or 100KB.
No. The quality search runs in a background Web Worker rather than on the page's main thread, so the tab stays responsive even while a large source photo compresses.
JPEG has no alpha channel, so a transparent PNG compressed with JPEG selected has its transparent areas filled with a solid color instead. If the tool detects transparency and JPEG is selected, it shows a warning with a one-click button to switch to WebP, which keeps transparency intact.
No. The image is decoded to raw pixels and re-encoded during compression, so EXIF metadata, including GPS location and camera details, does not carry over to the compressed file.
No, this tool handles one image at a time. For a batch of files that all need to fit the same limit, run each one through individually.
