Lossless baseline for further work.
JXL preserves every detail of the source HEIC, which prevents additional quality loss during subsequent edits or re-encoding. The original HEIC compression cannot be undone, but no new artifacts will be introduced.
ZAŠTO PRETVORITI
01
JXL preserves every detail of the source HEIC, which prevents additional quality loss during subsequent edits or re-encoding. The original HEIC compression cannot be undone, but no new artifacts will be introduced.
02
JXL is accepted by a wider range of image viewers, editors, and content systems than HEIC. The conversion removes a recurring compatibility friction without changing what the file actually contains.
03
JXL is well documented and decodable by long-lived tooling, which matters for archives, deliverables, and any file that needs to outlive the software that created it.
Posjeti ovu stranicu u bilo kojem modernom pregledniku — bez instalacije, bez registracije, bez dodatka.
Povuci svoj HEIC u područje za ispuštanje, ili klikni da odabereš jednu sa svog uređaja.
Pretvorba se izvršava u potpunosti u tvom pregledniku. Kada završi, tvoja JXL datoteka se preuzima na tvoj uređaj.

Zašto LocalConvert
| Category | LocalConvert | Cloud pretvarači |
|---|---|---|
| PRIVATNOST | Files never leave your device. The whole pipeline runs in your browser via WebAssembly. | Files travel to a remote server, sit in queue storage, and may be retained for analytics or moderation. |
| CIJENA | Free, no signup, no daily quotas. | Often free for small files; paid tiers for batch / large / commercial use. |
| OGRANIČENJA | Limited only by your device's memory and CPU. Multi-GB files OK on desktop. | Typical 100 MB to 1 GB per-file caps, plus rate limits. |
Apple's default photo format on iPhones since iOS 11. Smaller files than JPEG with comparable quality, but limited cross-platform support.
Typical uses
iPhone photos, iCloud Photo Library.
A modern image format with state-of-the-art compression for both lossy and lossless workflows. Supports HDR and lossless JPEG transcoding.
Typical uses
Photography archives, web (where supported), future-proof storage.
Da. LocalConvert je potpuno besplatan, bez registracije i bez ograničenja po datoteci ili po danu.
Ne. Pretvorba iz HEIC u JXL odvija se u potpunosti unutar tvog preglednika koristeći WebAssembly — tvoja datoteka nikad ne napušta tvoj uređaj.
Nema fiksne granice — praktično ograničenje je dostupna memorija tvog uređaja. Vrlo velike datoteke mogu trajati dulje ili ne uspjeti na uređajima s malo RAM-a.
Da — kad se stranica jednom učita, pretvorba iz HEIC u JXL radi bez internetske veze. Ponovo otvori stranicu jednom da je predmemorira.
LocalConvert koristi industrijski standardne alate (FFmpeg, ImageMagick, Pandoc) — kvaliteta odgovara onoj koju profesionalci koriste u naredbenom retku. Formati s gubicima ipak će izgubiti dio kvalitete pri svakom ponovnom kodiranju.
