Exact-size image engine
Set the ceiling. We find the fit.
Start with the destination,
not a quality percentage.
Compress to 50KB
At 50KB, keeping every original pixel usually creates obvious blocks and ringing. FileFit can reduce dimensions so faces, signatures, and important edges remain cleaner at the required file size.
- Small profile photos and application thumbnails
- Signatures or ID crops with a strict 50KB field
Compress to 100KB
A 100KB budget is often enough for a clear headshot, document preview, or listing image when dimensions and JPEG quality are balanced instead of changed independently.
- Application photos and online profile uploads
- Product or listing thumbnails with a 100KB cap
Compress to 200KB
At 200KB, many photos can keep substantially larger dimensions than at 50KB. That extra room matters for document previews, product texture, and images viewed beyond a tiny thumbnail.
- Readable document or receipt previews
- Marketplace and catalog images with fine texture
Custom image size
Custom targeting avoids guessing with quality percentages. Describe the real constraint in KB or MB and the same adaptive engine plans around that maximum.
- Unusual application limits such as 75KB or 350KB
- Megabyte limits such as 1MB or 2MB
Image too large
Most upload forms reject a file without saying what they would have accepted. Rather than guessing with quality percentages, start at a limit that clears the majority of forms and adjust once. If you do know your limit, use the exact-size tool for it instead — the result will keep more detail.
- Forms that reject a photo without stating a size limit
- “This file exceeds the maximum allowed size” errors
Reduce for email
A single phone photo is 3–8 MB, so one usually fits. The trouble starts with several attached at once, or with a recipient on a slow connection or a phone. Around 1 MB a photo still looks right at full screen while a whole set stays comfortably under any provider's cap.
- Several photos attached to one message
- “The attachment is too large” bounce-backs
HEIC will not open
Every other tool here makes a file smaller. This one leaves the photo essentially as it is and changes only the container, because nothing is wrong with the picture — the receiving computer simply cannot read the format iPhones save in by default.
- iPhone photos copied to a Windows PC that refuse to open
- HEIC files rejected by an older editor or upload form
Resize image
A CMS, a slide template, or a widget that says '1920×1080 recommended' is not describing a file-size ceiling — a small JPEG can still be far too many pixels wide. This tool solves the actual constraint directly: it computes the largest size that fits inside your width and height limit and stops there, so nothing gets cropped out and nothing gets stretched to fill space it shouldn't.
- Photos that need to fit a CMS or template's maximum pixel size
- Screenshots or camera photos far wider or taller than a slide or widget allows
Fix Instagram blur
Feed photos are served at 1080px wide, in a 4:5 portrait to 1.91:1 landscape range, and uploads reported to sit above roughly 1MB get recompressed on Instagram's end. None of that is announced at upload time — the photo just quietly comes back softer. Handing Instagram a file that already sits inside its own numbers is the actual fix, not a sharpening filter applied afterward.
- A feed photo that looks noticeably softer right after posting than it did in your camera roll
- Photos exported from an editor at full resolution and multiple megabytes
WebP will not open
Browsers all read WebP, which is why sites use it. Older photo viewers, document editors and upload forms frequently do not, so the file works everywhere except where you want to use it. Converting is the whole fix — the picture itself is fine.
- An image saved from a website that no app will open
- A WebP rejected by a form that only takes JPG or PNG
The number changes
the right decision.
A 50KB signature and a 200KB document preview should not be treated as the same compression job. The lower limit may demand a tighter crop or smaller dimensions; the larger limit should spend its extra budget preserving readable detail.
The transformation engine is shared, but each route gives target-specific expectations, checks, and recovery advice. Choose custom when the form gives a different KB or MB ceiling.
